Comment (by michaelld):

 0) When you remove cruft, you generally have to rebuild projects that
 might have used the cruft. That means either determining which
 dependencies to rebuild. There's no good way to determine this for GR, as
 stock GR has 300+ such dependencies when installed by 'port'. You can try
 "sudo port rev-upgrade" to see if anything already-installed by MP was
 linking to something in /usr/local, and rebuilding such projects might do
 the trick; might not too.

 1) There's still a lot of GR dependencies in /usr/local ... like Python
 and CppUnit, probably others. I don't know if these are impacting building
 GR, but they might be.

 2) My advice moving forward is to pick your package manager and stick with
 it. Remove -all- package manager installs, and start from scratch with
 whichever you pick. Doing so will be frustrating and time consuming: yes!
 But, it's the way with the greatest chances of success, for better or
 worse.
