I have the habit of cursing dylib myself and of accusing it of misbehavior, but I don't think this analysis is correct. If a binary has been linked with /sw/lib/libpng.3.dylib, then this library is loaded by dylib, even if /usr/local/lib/libpng.3.dylib is present on the computer. If it isn't, there must be a reason. The reason can be that - either /usr/local/lib/libpng.3.dylib has already been loaded before by some other object, and then that object should be identified and rebuilt linking to /sw/lib/libpng.3.dylib instead of /usr/local/lib/libpng.3.dylib. But the output Aaron showed does not indicate this scenario. - or that the environment variable DYLD_LIBRARY_PATH is set. There was a time when also DYLD_FALLBACK_LIBRARY_PATH could have this effect, even when it was not set explicitly, but I think this was the case only in some early versions of OSX 10.4 and associated xcode-2.0. Fink correspondingly used to set DYLD_FALLBACK_LIBRARY_PATH to an empty ":" for a while, but it doesn't do so any more. My bet is still that something in Aaron's startup scripts sets DYLD_LIBRARY_PATH. I don't know if he ever showed the output of echo $DYLD_LIBRARY_PATH I would try to run env DYLD_LIBRARY_PATH="" pymol and see what happens. -- Martin ------------------------------------------------------------------------- Take Surveys.
