undisabled building manager bug

Went to try to fix issue #504, rebuilt everything on the utk mac, and all tests pass. I blew all my install/build directories away to make sure, and it passed as well. The original problem was fixed in PR #566, but there were still issues. I've now fully tested this on all the platforms I can (Debian - CAE, Ubuntu - home, Darwin - insam), and all tests pass, so I'm ready to say this fixes #504 and can be pulled).
