So the correct setup for me (on centos 4) is to edit the 
/etc/http/conf.d/python file and put the following lines in the top of 
the file:

AddHandler mod_python .psp
PythonHandler mod_python.psp
PythonDebug On

See the page:

http://www.modpython.org/live/current/doc-html/hand-psp.html#hand-psp

Then for me it just works.  I haven't looked at SV for what must be a 
month now, some there is prolly some code rot in there.  If I get a 
chance I'll give it a quick check.  Also its not that functional atm ;-)

Cheers

Tom
