This is my fault.

The problem is caused by line #5 in the /sw/bin/coot wrapper script.  

Instead of 

export PYTHONPATH=/sw/lib/python2.7/site-packages:/sw/lib/python2.7/site-packages/gtk-2.0:/sw/share/coot/python:$PYTHONPATH

try

export PYTHONPATH=/sw/lib/python2.7/site-packages:/sw/lib/python2.7/site-packages/gtk-2.0:/sw/share/coot/python

and it should work.

Coot is inheriting $PYTHONPATH from some other location, probably CCP4, and is getting messed up.  I'm about to update the fink package, as soon as I confirm today's svn (r4386) compiles and behaves.

Sorry.
