 Replying to [comment:2 ryandesign]:
 > Looks like the [browser:macports-
 ports/_resources/port1.0/group/cxx11-1.1.tcl cxx11 1.1 portgroup] sets
 cxx_stdlib to macports-libstdc++ if it was libstdc++.  The portgroup has
 done this ever since it was
 [changeset:820bd91844cec723607fd76c8e5594f1f80d438c/macports-ports added];
 I don't know why. Marcus, do you remember?

 notEnoughCoffeeErr: Obviously it's because macOS libstdc++ doesn't support
 C++11 so MacPorts libstdc++ has to be used.
