[vtkusers] VTK Python Wrapping OSX 10.9

[Laurent Chauvin]

Hi Michka,

Thank you for your answer.

I would prefer not to use a binary version of VTK, more a compiled version.

I, indeed, have multiple versions of python (2.7.5 installed with xcode,
and 2.7.3 installed with Slicer).
However, I don't compile any code, and I don't use cmake. I just do
something like 'python script.py'.

I tried in both terminal, and it worked in none of them, but it worked in
Slicer python interpreter. I guess Slicer set proper environment variable,
but I cannot figure it out which one I should set.

-Laurent
