Just so everyone on the list knows.

Extrapolating from what Charles said, the error was probably that MegaPOV 
wasn't able to include the transforms.inc file because MegaPOV wasn't

And on Mac OS X, Linux, and other UNIX systems, to use the 
CHIMERA/bin/povray.exe program outside of chimera, you need to setup the 
shared library path to include CHIMERA/lib.  Chimera does that setup 
automatically for many of the programs in CHIMERA/bin, so we should 
probably fix it for povray as well, but if you're going to use your own 
POV-Ray anyway, like the multi-threaded 3.7 beta release, then that is 
not an issue.
