Coincidently that was the exact same program that hosed my python
installation too.
I had set up my computer to run the python based AutoDock Tools
interface to the docking program AutoDock. The installer for this
program puts its own copy of python as a subdirectory in the main
application directory and adds some environment variables to the
.cshrc file. Apparently, some variable created here affected other
python based apps. When I commented these out and opened a new xterm
and ran pymol, everything worked normally.
Moreover, my attempts to re-engineer the AutoDock installation ended in
a complete morass. This is a great reason for installation software to
at least allow you the option of using your already installed system
python.
