Doesn't surprise me.

I'd recommend first reporting your problem upstream to the mod_python
authors, as this does not appear to be a FreeBSD or FreeBSD ports issue.

As for solution, the solution here is to not use mod_python.  Surely
something like cgiwrap or FastCGI could be made to work with python.
