This was very helpful. I also had to do:

rm /usr/local/etc/my.cnf

Something I had done previously had resulted in a my.cnf file that prevented MySQL from working (I was getting the dreaded ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) error).

Thank you! This was what I needed!
