[vtkusers] Installation vtk 5.2.0 on OS X and PYTHONPATH

Hey Antoine,

I always get that error you originally got during "sudo make install"  
of VTK, but for me it always works to just go into the build/Wrapping/ 
Python directory and run "sudo python setup.py install". This has  
worked for me with the Python that ships with Leopard, as well as  
others. (For the Leopard python, by default it installs into /Library/ 
Python/2.5/site-packages, which is fine.)

Dave: If you're still having trouble getting VTK 5.0 to install  
correctly with the Python wrappings, you might want to consider  
downloading the Academic version of the Enthought Python distribution  
-- It will install its own version of Python (which you might not  
want), but it comes with a BUNCH of packages, including VTK 5.0.4.
