[vtkusers] Problem building VTK (CVS) on Mac OS X with Python

[Sander Niemeijer]

You were right. The fact that I was trying to link the static python  
library against a shared library was indeed the problem. I am now  
trying to use the framework version of Python (which already includes a  
shared library, so I don't have to perform the extra dylib creation  
step that is used for the fink version).
I changed the cmake PYTHON_LIBRARY option to  
-DPYTHON_LIBRARY:FILEPATH='-F/Users/sander/pythonfw -framework Python'  
(I've got my homemade framework installed in /Users/sander/pythonfw)  
and building VTK seems to go fine now (it is still happily crunching  
away, so fingers crossed ;-) )

P.S. I'm still pointing the PYTHON_EXECUTABLE and PYTHON_INCLUDE_PATH  
to my non-framework installation of python, but as far as I can see it  
will be relatively easy to get them to point to the locations within  
the framework. I'll try that as soon as my build finishes.

Thanks!

Regards,
Sander
