Ok, but the Python22\Lib\site-packages\VTK is not on PATH (though it
is in PYTHONPATH).  I'm not sure if PYTHONPATH translates to PATH.  Or
are you saying that the the current directory is always in the path
and when Python loads the module, the DLLS on the same directory are
found correctly?

Please, if you can do this then it should be very easy to write a
setup.py that installs the right packages in the right places without
the need for either linking libraries here and there or editing
/etc/ld.so.conf.  It would be very nice if this were possible.
