Use source code for mod_python from mod_python subversion repository
as that version includes all MacOS X Leopard fixes.

Even better, if you are only wanting to host an application that
support WSGI interface and not using mod_python specific APIs, use
mod_wsgi instead. Pretty well all Python web applications and
frameworks support WSGI interface these days and mod_wsgi is arguably
a better solution these days.
