Hi,

I am currently trying to run the plugin SuperSymPlugin12.py. However it requires cctbx. 

I currently source cctbx from /usr/local/xtal/cctbx/cctbx_build/setpath.sh with pymol in /usr/local/xtal/pymol_1.41/pymol

I have tried the getting pymol to recognise the cctbx.python however I have run into difficulties.

I tried modifying the pymol script to 
#!/bin/sh
PYMOL_PATH=/usr/local/xtal/pymol_1.41
export PYMOL_PATH
#exec /usr/bin/python $PYMOL_PATH/modules/launch_pymol.py "$@"
exec python $PYMOL_PATH/modules/launch_pymol.py "$@"

where python is /usr/local/xtal/cctbx/cctbx_build/bin/python

However I get this error: 
Traceback (most recent call last):
  File "/usr/local/xtal/pymol_1.41/modules/launch_pymol.py", line 32, in <module>
    import pymol
  File "/usr/local/xtal/pymol_1.41/modules/pymol/__init__.py", line 472, in <module>
    import _cmd
ImportError: No module named _cmd

Any help would be greatly appreciated!!
