Comment (by ecronin@…):

 I remember a bit more now...  It's supposed to build with clang 3.1 and
 later.  The stopper I ran into the one time I tried several months ago was
 that the libc++ that the Lion XCode/Lion itself (not sure which "owns"
 /usr/lib/libc++) provided was not new enough to implement the needed C++11
 stdlib features, so it would need some macports-provided newer version of
 libc++.  (I was confusing it with another program that needed an
 unreleased clang snapshot which is why I said clang-devel in the other
 ticket).

 I don't know which boost libs mkvtoolnix is using these days, and how much
 there are differences in those libs when -std=c++11 is involved.  But it
 would at least be ABI compatible I think, which mp-gcc won't be any time
 soon.  You might get lucky and it will work well enough for mkvtoolnix,
 which is much better than today's mp-gcc which definitely will never
 work...  It's still not a general solution to the boost versioning problem
