[mod_python] mod_python thread error (probably my fault)

I'm trying to do some SOAP services with the ZSI stuff.  From a prompt my script reports no errors, but when I call the script from a browser (not expecting the SOAP to work through here, just testing for other errors) I get a mod_python error with a trace going back to threading.py about not being able to import module thread ("ImportError: No module named thread").

Now, I got 2.3.2 through Apachetoolbox but that didn't work too well so I compiled and installed the newest apache and mod_python and python (no errors in this process).

Other scripts not using scripting work fine.

Any ideas?
