[vtkusers] VTK Python Wrapping OSX 10.9

[Michka Popoff]

Sending my mail a second time, the first seem not to have gone through ...

David Gobbi is right:
If you type python in the terminal, OS X's python 2.7.5 is launched.
VTK for slicer was compiled against the shipped python 2.7.3 I suppose.

So you try to run from a 2.7.5 python a VTK library which was build against 2.7.3. That won't work (that's the error you get).
You can not mix the two.


What I meant by binary version is in fact a compiled version (which will work out of the box).
