MySQLdb install under Mac OSX 10.5, Python 2.7

I'm trying to get MySQL-Python 1.2.3 running under Leopard on my MacBook Pro for Python 2.7 (64 bit). I've tried building and installing from source along with easy_install with no luck. When installing from source, I have modified mysql_config.path in setup_posix.py as suggested in another related answer to

mysql_config.path = "/usr/local/mysql-5.1.41-osx10.5-x86/bin/mysql_config"

The build and install seems to go ok. Yet after typing 'import MySQLdb' in Python, I get the following.

>>> import MySQLdb
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.5-fat3.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.5-fat3.egg/_mysql.pyc, but /Users/diehl4/Downloads/MySQL-python-1.2.3 is being added to sys.path

Any thoughts on what might be the issue? I'm running out of ideas. Here is the information from the build:

And here's the answer. I started with a 64 bit install of Python and a 32 bit install of MySQL. I just discovered the latter. Installing a 32 bit version of Python 2.7 made the above issue go away.
