Comment (by kencu):

 This is where we are running into some resistance/differences of opinion
 on MacPorts. There are those who will want only the ideal "build fix"
 solution used, and no other fix is acceptable -- then this ticket sits for
 months or years, as nobody will usually bother to spend the time to fix it
 like that on an old, unsupported system.

 You could blacklist all compilers prior to `clang-5.0` on systems < 10.9
 that are configured to use `libcxx`. That would work, and the logic flows
 smoothly enough. It is also kinda ugly in the Portfile. You see what I
 mean. When I do propose these kinds of fixes, the PRs tend to sit in the
 PR queue for weeks and go nowhere until I just close them out of
 frustration.

 Sooner or later we'll default to `libcxx` on all Intel systems 10.5+ --
 then this will be easier to fix cleanly for everyone in base, because
 we'll just build with `clang-5.0` and newer by default always.

 In the meantime, I have set my "default compiler" in `macports.conf` to be
 `clang-5.0`, and that just fixes all these builds with ease. I suggest you
 consider doing that too.
