Autodock tools

Dear CCLers,

Does anybody use Autodock tools on MacOSX. I was going over the exercises from the tutorial and I am getting python errors when I am trying to use from 'ligand' menu (in exercise 3):

grid->macromolecule->choose macromolecule

Maybe I can chat with someone off list who has experience in using the MacOSX version.

Thank you for your help.
