Comment(by dev@…):

 I experienced this problem. Something went wrong with my installation via
 mac ports.

 I found in the error.log:


 {{{
 Can't start server : Bind on unix socket: Permission denied
 Do you already have another mysqld server running on socket:
 /opt/local/var/run/mysql5/mysqld.sock ?
 }}}

 Check if you can read/write to /opt/local/var/run/mysql5/ with user mysql:

 sudo -u mysql touch /opt/local/var/run/mysql5/test
 sudo -u mysql ls l /opt/local/var/run/mysql5

 If not so check the permissions in superior folders. In my case
 /opt/local/var/run had strange permissions 730 (drwx-w----) but should be
 755.
