The Python modules should already be .so files that have symbolic links 
to them (made by "python setup.py install").

libvtkRenderingPythonTkWidgets.dylib isn't a Python module as far as I 
can tell.

.pth file perhaps, but symbolic links are fine.

Note that there other problems. The .so's and .dylib's point back to the 
build directory for the library dependencies. I used macholib from 
py2app to rewrite the headers to point to the installation directory.
