Comment (by kencu):

 The `cxx11 1.1 PG` doesn't fix this port. You just wind up with a messy
 build line with both `-stdlib=libc++` and `-stdlib=macports-libstdc++`
 both specified, and screenfuls of link errors.

 For some data points:

 It does install on 10.9 without modification.

 It does install on 10.8 without link errors when you force `libc++` and
 also force the compiler to `clang-5.0`.
