Dear All, I tried installing 0.90 from source, using "option 1", i.e.
python setup1.py install python setup2.py But when I try to run the executable pymol.com, I get the error: Traceback (most recent call last): File "/usr/lib/python2.2/site-packages/pymol/__init__.py", line 92, in ? import pymol File "/usr/lib/python2.2/site-packages/pymol/__init__.py", line 300, in ? import _cmd ImportError: /usr/lib/python2.2/site-packages/pymol/_cmd.so: undefined symbol: MemoryCacheDone Any advice appreciated, Richard Baxter
