Comment (by ballapete):

 The MacPorts documentation seems to be far outdated, when it comes to
 documenting compilers suited to build a port:

 {{{
 Values: gcc-3.3 gcc-4.0 gcc-4.2 llvm-gcc-4.2 clang macports-clang-3.3
 macports-clang-3.4 macports-clang-3.7 macports-clang-3.8 macports-
 clang-3.9 macports-clang-4.0 macports-clang-5.0 macports-clang-6.0 apple-
 gcc-4.0 apple-gcc-4.2 macports-gcc-4.3 macports-gcc-4.4 macports-gcc-4.5
