Just to add my thanks and experience so far:  Thank you so much for this!  As Martha and others have seen, everything with Athena seems to work fine for me on 10.8.5, but Hephaestus and Artemis segfault on launching (after splash screen). 

Should I try installing demeter from the git repo into the macports perl location?  Or is there more to it?  Frank, would it be possible to post some configuration notes?

Thanks again,
