[mod_python] Error using Session

Today I upgraded to Python 2.3.3 and mod_python 3.1.2b fine. I am trying to use the Session
class now and when in my request handler I do something simple like:

sess = Session.Session(req)
req.write (sess.id())

I get the following error. Any idea why this happens and why python2.2 is still being 
used in mod_python? The 2.3.3 is installed in /usr/local/lib which comes first in my PATH.
I am using Redhad which seems to depend on 2.2!


Traceback (most recent call last):
