[vtkusers] OS X Python Carbon Valid Pixel Format??

[garsha]

Greetings,
I'm still hanging on to the hope that I can get VTK (4.2.1) w/ Python 
(2.2.2) to work on OS X 10.2.4 with CMake 1.6.  Everything builds fine 
and installs smoothly--much easier than it was several months ago.  I 
can import vtk in the python interpreter, and I can go through a simple 
cone example up until the moment of truth when I attempt to initialize 
the RenderWindowInteractor: I get an error stating that the 
CarbonRenderWindow couldn't find a valid pixel format.  When I Google 
this predicament, I can see that others have experienced this problem, 
but I haven't been able to find the solution.
    From what I can tell this may be something related to the OS X 
implementation of OpenGL--has anyone else seen this?  Is there perhaps 
an environment variable I need to set?  I'm running an older powerbook 
without hardware acceleration for OpenGL but I've seen the cone.py run 
on it (long ago when I could run the early OS X binaries posted at 
http://www.atamai.com/vtkOnOSX.html). So it seems to be a software hangup.  
    It is my aspiration to run VTK and MayaVi on OS X...has anyone out 
there had success building and running VTK with Python wrappers on an 
updated version of OS X?  Carbon or X11?  
    Any leads on a way to stomp this valid pixel format issue would be 
much appreciated-thanks in advance.
Regards,
