Comment (by michaelld@…):

 Mine failed pretty quickly too, but for different reasons. I'm still
 playing with it, slowly. Here's the issue with yours, putting the various
 threads together into a single chain:

 So, the issue here is that the OBJCXXFLAGS does not contain
 "-stdlib=libc++". I think this is a bug in qmake. It looks like the
 Portfile is "doing the right thing", but qmake isn't. Hmmm ...

 If you want a quick way around this error, just copy the compile command
 by hand & add in the missing argument; you'll need to "cd" into the
 correct directory first, of course.
