 I see that it's building with Xcode clang 600.0.57, despite the fact that
 the Portfile blacklists `{clang < 700}`. This is probably because in
 [aec14792b8457e3c77b5c90a3c402a88ba9eb41b/macports-ports] the blacklist is
 getting ''reset'' to just `macports-gcc-6`. I'm sure this was meant to
 ''append'' to the blacklist instead of overwriting it.
