With my usual way of installing pymol is to build most of the dependencies from source, including python. This copy of python gets sym-linked to pymol.python for building pymol (aka pymol.python setup.py build , etc in the pymol source directory) and is only used for running pymol. If you've installed things this way, then "pymol.python setup.py install" for your package should work, assuming your environmental python environmental variables are kept straight. But this is something I haven't needed to test, so if Warren says it's not possible he's probably found a problem with this approach I missed. Pete
