Comment (by kencu):

 I'm surprised anyone with 10.6+ would consider anything other than
 clang-3.7-8-9 and libc++ at this point -- Jeremy has fixed that up very
 nicely and 10.6 + seems to work great with libc++ for any software I have
 tried; I have no concerns about using that going forward for all software,
 and would suggest (IMHO) that macports just default to that forever and be
 done with it. But that's not up to me.

 A few last hiccups with some last few build systems like scons persist --
 I have personally fixed all those, as you know, by patching clang, but
 sooner or later macports will get all the portfiles in line for that.

 10.5 (and 10.4) are the only issue I have left with cxx11 -- although just
 tonight I have clang-3.6 installed and compiling c++ software on 10.5 PPC
 linking against libc++, so I still hold out hope there. In the meantime,
 tho, 10.5 and 10.4 are where I'm using gcc6.
