Comment (by kencu):

 For now, base defaults to choosing an inappropriate version of clang on <
 10.6. Only clangs >= 3.8 understand -stdib=macports-libstdc++ (and that's
 my special 3.8 from TigerPorts, as macports doesn't have clang-3.8
 anymore).

 To make it build on 10.4 Intel you could use TigerPorts to install
 clang-3.8 or clang-5.0 or clang-7.0, or you could try forcing gcc7 like
 this -- I haven't tried it recently, so it might or might not work:
 {{{
 sudo port -v install boost configure.compiler=macports-gcc-7
 }}}
