[mod_python] Sessions on Mac OS X

hi ,

Does someone on this list have experience using session (in psp or in  
scripts) on Mac OS X  10.3.9 , Python 2.3  (Apple) and mod_python  
3.1.4.

I have had problems with it ; where as the same code works fine on  
linux machine with same configuration.  Is this some MAC specific  
problem?

Mod_python error: "PythonHandler mod_python.psp"

Traceback (most recent call last):

   File
