The warning looks familiar.  Are you running python from the MySQLdb
source directory?  ie.  /opt/downloads/py-modules/MySQL-python-1.2.3c1

I think you just need to change directories and the warning will go
away.  Check what's happening on line 3 of _mysql.py  I don't have the
source in front of me.
