Make install simply installs the libraries.  It doesn't install the
python modules in Wrapping/Python anywhere.

The problem occurs because the either Python or the linker is confused
by two sets of the same libraries in different places.  So, if you
want to use LD_LIBRARARY_PATH's then you have to be careful that the
same library isn't present in the linkers default path somewhere
else.  I usually dont install the libraries when I build from source.
Instead, I source a simple script that sets the PYTHONPATH and LIB
PATH correctly.

One more point to note: you need to put both the Wrapping/Python and
bin dir in your PYTHONPATH.  You could eliminate this by making links
from the Wrapping/Python dir to all the actual libs in the bin dir.
Like so:

ln -s $HOME/software/vtk/k7/bin/libvtk*Python*.so $HOME/software/vtk/VTK/Wrapping/Python/

If you do that you will not need to put the bin dir in your
PYTHONPATH.
