[mod_python] Breaking things after upgrading MySQLdb (to 1.2.2)

Glad to see you worked out my instructions. :-)

I probably suggest not using /var/tmp though because if this is a
shared machine, too easy for some one to place in /var/tmp a Python
module which overrides some important standard Python module. Ie.,
would be used in place of the real one. Thus, someone could either
inadvertently or deliberately interfere with your application.
