jabberd will not start on reboot, only starts manually

[Pollywog]

I am running FreeBSD 6.2 with Jabberd installed from ports:
jabberd-2.1.18


When I reboot the machine, jabberd will not start, but it will start if I 
manually restart it with /usr/local/etc/rc.d/jabberd restart

/var/log/messages shows:

jabberd/c2s[989]: mysql: connection to database failed: Can't connect to local 
MySQL server through socket '/tmp/mysql.sock' (2)
jabberd/c2s[989]: failed to initialize auth module 'mysql'

I added 'mysql' to the REQUIRED line in the startup script for jabberd but 
this did not solve the problem.  It still appears as though jabberd attempts 
to connect to mysql before mysql is ready for the connection.

Can anyone assist with this problem?

thanks
