[vtkusers] VTK Python Wrapping OSX 10.9

[Laurent Chauvin]

Thank you David and Michka.

I just figure it out.
Indeed you are right Michka, when I call 'python' from the terminal, it
called the 2.7.5 from the system instead of the one VTK has been built with.

I went to python 2.7.3 directory and used ./python (instead of just
'python' command) and I got the 'No module named vtk', but then I added the
path in PYTHONPATH and it worked.

Thank you very much for your help.

Also, is it possible to replace the default 'python' command with the 2.7.3
version, so I don't have to go in the directory all the time ?

Thank you.
-Laurent
