Comment (by kencu):

 clang on 10.5 is a totally different animal, and not quite ready for prime
 time. The installation and standard library settings are not the same as
 LibcxxOnOlderSystems at present. I'll get back to you. For now, the cxx11
 1.1 portgroup should lead to gcc6 building cxx11 ports, and that works for
 the most part.
