Well, Debian builds a shared shared version of libpython.  And yes,
prior to the vtkpython.cxx commit I never needed to use the libpython
library to link with.  I used to leave it empty and everything worked.
However, the build problem seems to disappear after I added it and the
resulting vtkpython library seems to work ok.  So, my solution most
probably is a hack.
