Comment (by john+macports@…):

 I verified the command line tools were the right version. At this point
 I've completely blown away the entire /opt/local tree and
 recompiled/installed Macports (more than once). The issue I saw happened
 regardless of update/install from scratch/port tried. In the end I got
 tired of this silly game and went for the usual OS X nuclear
 option.[[BR]][[BR]]
 1) Reboot to recovery mode, repair disk, repair permissions[[BR]]
 2) Delete /Applications/Xcode.app re-download, re-install[[BR]]
 3) Manually download command line tools from dev.apple.com, install
 again[[BR]]
 4) Wipe then recompile, reinstall macports[[BR]]
 [[BR]]
 .. and joy. I'm honestly not sure what the deal was, but I suspect that
 since upgrading from 10.8 -> 10.9 -> 10.10 (and all the versions in
 between) something was unhappy.
 I'm fairly certain there  nothing wrong with the Macports code and I
 somehow brought this upon myself, so I appreciate the patience and help.
