[vtkusers] Installation vtk 5.2.0 on OS X and PYTHONPATH

Fri Sep 19 11:18:20 EDT 2008

I tested the vtk 5.0.4 compilation and installation : it went ok. Then  
I installed macpython 2.5.2 and compiled again vtk 5.2., and finally  
the installation went ok as well.
It seems the apple leopard python could be the culprit.

Antoine.
