[vtkusers] VTK Python Wrapper on OSX

[Eric E. Monson]

Hey Kabir,

Did you build VTK with VTK_USE_RPATH: OFF? If you build VTK with that ON (which I would recommend on OS X unless you are trying to package some things that require it OFF), then the Python libraries should automatically contain the correct path to find libvtkCommonPythonD.5.6.dylib

You can check this by running:

otool -L /Library/Python/2.5/site-packages/VTK-5.6.0-py2.5.egg/vtk/libvtkCommonPython.so

to see where it's looking for the VTK libraries. If you see that libvtkCommonPythonD.5.6.dylib is listed without an absolute path to where your VTK libraries are, then that's the problem.

-Eric

"sudo make install" from the [build] directory always fails to do the proper thing for my Python wrappers on OS X, but the former command works well for me.
