[vtkusers] install python wrapping on Mac 10.7

[David Gobbi]

I also see another potential problem.  It looks like you are trying to use the
python in "/opt/local/bin/python" instead of the one in "/usr/bin/python".

VTK works best with the python in /usr/bin, i.e. with the python that Apple
supplies with OS X.  If you try using VTK with a python from ActiveState
or MacPorts or Fink, then you will probably run into trouble.  It's best to
use these settings in CMake:

PYTHON_EXECUTABLE:FILEPATH=/usr/bin/python
PYTHON_INCLUDE_DIR:PATH=/System/Library/Frameworks/Python.framework/Headers
PYTHON_LIBRARY:FILEPATH=/usr/lib/libpython2.7.dylib
