 I notice the flag `-std=c++14` is used.

 The port should indicate this requirement by including the cxx11 1.1
 portgroup, and possibly additionally blacklisting `{clang < 602}`.

 The port may also need to change to appending to `compiler.blacklist` and
 `compiler.fallback` rather than overwriting them as it currently does,
 since you don't want to counteract what the cxx11 1.1 portgroup does.
