Python problems

[Maneesh Yadav]

(SOrry if some of you have already recieved this, it appears that I was
posting to an outdated list).  It was suggested to me to recompile, (I
will try with vtk 3.1) but I just wanted to be sure I wasn't committing an
obivous error.)

I currently have VTK 2.4 installed and running (the nvidia opengl lib was
the source of some of my initial problems, it currently doesn't impliment
all the mesa calls req'd by VTK).. A large number of examples in the
python directory don't work, here are a few that do: Cone.py Sphere.py
etc.
 
However most files give me the follwing kind of error,
 
File "spring.py", line 46,in ?
    extrude.SetInput(profile) SystemError: NULL result without error in
call_object as far as I can tell there is no data req'd for the example.  
Can anyone tell me what I am doing wrong?
