can't run the parallel version on a mac

[mircealungu]

error is:

sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)") (Background on this error at: http://sqlalche.me/e/e3q8)

this would probably be the same also in the serial version though.
the problem seems to be that the image does not have mysql started.
