[Chimera-users] Chimera 1.1951 on OSX 10.3.4 fails to do much at all...

(On the chance that Tom has already left for vacation, and won't be able 
to reply for a week.)

Glad to hear that it works when it's in /Applications.  We didn't intend 
for chimera to be location-dependent, so we'll look into that problem. 
Chimera includes it's own python and should use it.  That's why the Tom's 
email mentioned the PYTHONHOME, PYTHONPATH, and CHIMERA environment 
variables -- those should be the only possible way of confusing chimera 
and if they're not set, then that means that there is a less obvious bug 
to fix (the non-Mac versions of chimera prevent those environment 
variables from confusing chimera, and the Mac should too).
