Which mysql port are you trying to use?
This will show the installed and active mysql ports I am aware of:
$ port installed active and \( name:^mysql{5,51,55}{,-server}$ or name:^percona{,-server}$ or name:^mariadb{,-server}$ \)

Assuming mysql55-server:
$ sudo port load mysql55-server

What is the log file are you reading? Can you show the complete lines?

What command are you executing?

Is mysqld running?
$ ps ax | grep mysqld

Did Mountain Lion add my.cnf files that are causing problems?
$ cat /etc/my.cnf /etc/mysql/my.cnf
