Comment (by ryandesign@…):

 Comments in the portfile state that the port requires a compiler that
 supports C++11. The port should use the cxx11 1.0 portgroup to enforce
 this.

 The port will need to be UsingTheRightCompiler for that enforcement to
 take effect. The port should also be using the right -arch flags and
 should get a universal variant if possible.
