Comment (by ryandesign@…):

 Some ports might have gcc48 as the default variant (probably because gcc48
 was the latest stable version at the time). Some ports might not even have
 newer gcc variants. If so, those ports should be updated to have newer gcc
 variants, and gcc5 should be set as the default, because gcc5 is now the
 latest stable version.

 Then there's OpenBLAS, which uses dragonegg, for which
 dragonegg-3.4-gcc-4.8 is the latest version. However, dragonegg only gets
 used if you use clang. OpenBLAS does have a gcc49 variant that could be
 used. However, that might be bad on OS X 10.9 or later if OpenBLAS has C++
 code (I don't know if it does).
