When I try to start MySQL I get:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
When I use sudo I get:
Starting MySQL
. ERROR! The server quit without updating PID file (/usr/local/var/mysql/Victorias-MacBook-Pro.local.pid).
I am working with Mac OS X 10.7. I installed MySQL through homebrew and I installed MySQL 5.5.20.
This is the .err file I am getting:

Remove this pid file, make sure all the instances are stopped (kill any processes not going down), check nothing is listening the MySQL port 3306 (netstat should help) and try to start MySQL again.
