We are running Python v2.2.3 on Red Hat Enterprise 3 which is almost like Red Hat 9 and/or Fedora Core 1. Our RedHat version seems to be choking on the pyc file. The following is the error we get.
Exception in plugin 'CASTpyMOL' -- Traceback follows...
Traceback (most recent call last):
File "modules/pmg_tk/PMGApp.py", line 109, in initialize_plugins
ImportError: Bad magic number in /usr/lib/python2.2/site-packages/pymol/modules/pmg_tk/startup/CASTpyMOL.
Error: unable to initialize plugin 'CASTpyMOL'.
We have contacted the plugin authors but have been unable to solve this problem.
