Warren, in launch_pymol.py there is the following code
sys.path.append(os.environ['PYMOL_PATH']+'/modules') It looks to me like your adding $PYMOL_PATH/modules to the path of modules searched by python. Right now, there is no modules directory in the final installation. Should I create one and put all the .so files in there? Right now I define $PYMOL_PATH=/usr/lib/python2.1/site-packages/pymol Where pymol has a bunch of .so files and some directories (no modules directory) with various __init__.py files. But it still starts up fine. Its like the sys.path.append does not seem to do much. What do you suggest? Steve.
