[vtkusers] Installation vtk 5.2.0 on OS X and PYTHONPATH

Sorry for the delay - took me a while to get to this. Installed the  
enthought distribution. When running its Python, and typing: import  
libvtkCommonPython, it claimed it couldn't find the module. I exported  
PYTHONPATH to point it to enthought's copy of those files and then it  
worked, but it still claims the GetNumberOfPolys method doesn't exist  
for a vtkPolyData object.
