Sorry, don't know exactly what's happening here. Is this from a  
"fresh" python prompt?

How did you install MySQLdb, did you use easy_install? If so, try to  
install from the sourceforge download.

Try to remove it, remove the "build" directory from your mysqldb  
download and redo the whole
python setup.py build / python setup.py install process

To remove it, nuke this:
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site- 
packages/MySQL_python-1.2.2-py2.5-macosx-10.3-fat.egg

And try to reinstall?

Perhaps someone who knows what the problem is here can give you a  
better idea on what to do.
