[6.3] MySQL server doesn't start

[Gilles]

Hello

I successfully updated the Ports collection to compile MySQL 5.1.22,
but even after updating /etc/rc.conf, the server doesn't start but
doesn't say why:

======
# pkg_version -v | grep -i mysql
mysql-client-5.1.22                 <   needs updating (port has
5.1.30)
mysql-server-5.1.22                 <   needs updating (port has
5.1.30)
======
# cat /etc/rc.conf 
#BAD? mysql-server="YES"
mysql_server="YES"
======
[root at freebsd ~/www]# ps aux | grep -i mysql
root  52112  0,0  0,1   468   336  p4  R+   18:15     0:00,00 grep -i
mysql
======
# /usr/local/etc/rc.d/mysql-server start
[root at freebsd ~/www]# /usr/local/etc/rc.d/mysql-server status
# 
======

There no information in /var/log/messages either.

Any idea what I could try to investigate is going on?

Thank you for any tip.
