Instalação gem mysql2 no OS X 10.6.7

	Passos que segui para conseguir instalar a gem mysql2,
	pois o comando de forma tradicional gem install mysql2 não estava funcionando.

	1) locate mysql_config
	Não listava nada, porém tenho mysql rodando aqui com PHP.

	2) brew install mysql

	3) locate mysql_config
	/Applications/MAMP/Library/bin/mysql_config

Bug ao usar south por uso errado (alterando mysql manualmente)

	~/workspace/django/financeiro$ ./manage.py migrate
	Running migrations for customers:
	- Migrating forwards to 0001_initial.
	> customers:0001_initial
	! Error found during real run of migration! Aborting.

	! Since you have a database that does not support running
	! schema-altering statements in transactions, we have had
	! to leave it in an interim state between migrations.
