[PyMOL] CentOS installation help

Hello,

I have installed pymol (v1.5) as root.  When I am logged in as root pymol launches fine with the pymol command.  In the same directory as not root, any other user, I get the following error message:

/usr/local/bin/pymol: line 14: /usr/local/src/pymol/setup/ext/bin/python: No such file or directory
/usr/local/bin/pymol: line 14: exec: /usr/local/src/pymol/setup/ext/bin/python: cannot execute: No such file or directory

Any ideas on what's wrong?

Thanks,
John
