There simple steps:

1) Compile the bind

I've placed the chroot environment in /opt/named, so i've choose to install there the named.
I used the configure script to put the destination:

~/bind-9.3.1 root# ./configure --prefix=/opt/named

After you need only to compile with normal command "make && make install"

2) Create the environment

I've created a simple directory tree into /opt/named

--dev
--etc
--var
-+--log
-+--run

The other directory are created by the installation script of named

Into /opt/named/dev i've created these device: null, random, zero. I don't know the major and the minor for mknod, so i've seen into /dev/ the number with 'ls -la /dev/null', and so on.

Copy the file /etc/localtime into the etc directory of your chroot

3) Configure the bind

You can use your normal named.conf, but i need to add some lines, else there are some problems with the path into the chroot:

options {  

  pid-file "/var/run/named.pid";

  named-xfer "/bin/named-xfer";

  statistics-file "/var/run/named.stats";

  dump-file "/var/run/named.db";

};

The MacOsX syslogd don't support the -a flag for additional "/dev/log", i've configured the named for using the log files. There is some configuration that i've found in a gentoo howto, they will be really usefull:

logging {



  channel default_file { file "/var/log/default.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel general_file { file "/var/log/general.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel database_file { file "/var/log/database.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel security_file { file "/var/log/security.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel config_file { file "/var/log/config.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel resolver_file { file "/var/log/resolver.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel xfer-in_file { file "/var/log/xfer-in.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel xfer-out_file { file "/var/log/xfer-out.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel notify_file { file "/var/log/notify.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel client_file { file "/var/log/client.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel unmatched_file { file "/var/log/unmatched.log" versions 3 size 5m; severity dynamic; print-time yes; }; 

 channel queries_file { file "/var/log/queries.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel network_file { file "/var/log/network.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel update_file { file "/var/log/update.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel dispatch_file { file "/var/log/dispatch.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel dnssec_file { file "/var/log/dnssec.log" versions 3 size 5m; severity dynamic; print-time yes; };

  channel lame-servers_file { file "/var/log/lame-servers.log" versions 3 size 5m; severity dynamic; print-time yes; };

  

  category default { default_file; };

  category general { general_file; };

  category database { database_file; };

  category security { security_file; };

  category config { config_file; };

  category resolver { resolver_file; };

  category xfer-in { xfer-in_file; }; 

  category xfer-out { xfer-out_file; }; 

  category notify { notify_file; };

  category client { client_file; };

  category unmatched { unmatched_file; };

  category queries { queries_file; };

  category network { network_file; };

  category update { update_file; };

  category dispatch { dispatch_file; };

  category dnssec { dnssec_file; };

  category lame-servers { lame-servers_file; }

;};

4) Starting Up

The macosx has the facility daemon to application named launchd. I've put the file org.sfrajone.named.plist into /Library/LaunchDaemons which contain system wide daemon provided by the administrator, not the system one.
Here the file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>org.sfrajone.named</string>
        <key>OnDemand</key>
        <false/>
        <key>ProgramArguments</key>
        <array>
                <string>/opt/named/sbin/named</string>
                <string>-f</string>
                <string>-t</string>
                <string>/opt/named</string>
                <string>-u</string>
                <string>named</string>
                <string>-c</string>
                <string>/etc/named.conf</string>
        </array>
        <key>ServiceIPC</key>
        <false/>
</dict>
</plist>

Now we need to remove from the startup the system named:

root# launchctl unload -w /System/Library/LaunchDaemons/org.isc.named.plist

Then we need to put the our named:

root# launchctl load -w /Library/LaunchDaemons/org.sfrajone.named.plist 

And startit with:

root# launchctl start org.sfrajone.named

Now the named has been started, at the next reboot will start automatically.
