My first attempt failed because for some reason Anaconda was making Macports look for a non-existant openssl.cfg file.  I uninstalled that and things worked fine.  You'll just want to ensure you do a reboot between uninstall and reinstall.

I made a bit of a mess to start, and had to end up going in this direction as well. I forgot (idiot that I am) to update to the appropriate developer tools (Xcode 7 GM). So, I'm in the process of rebuilding/reinstalling packages now. I have enough packages installed (due to dependencies) that the build is now on its 8th hour (atlas failed due to lack of fortran... I'll have to go back and look into it- I think I wasn't using the macports gcc in the past but certainly don't trust myself.). 

I'll report any failures as I see them. 
Best Regards,

Joe
