Comment (by kencu):

 Why don't you try using a newer compiler? That sounds like it should work.

 You would install some version of {{{clang}}} from the MacPorts collection
 -- try {{{clang-9.0}}} and if that doesn't build it, use something older
 and more forgiving like {{{clang-5.0}}}.

 You would do this:
 {{{
 sudo port -v install clang-9.0
 sudo port -v install cegui configure.compiler=macports-clang-9.0
 }}}

 once you see which compiler works, we can work on fixing the Portfile to
 reflect that.
