Thanks for the information, that is why I had asked. I have never really dug this deep into sage before, (nor software building in general) so I am completely green.
Saw this posting on macports + the output of otool -L made me think that this could be the problem. But I agree that it isn't likely. -- David Monarres dmmonar...@gmail.com "There...
