Comment (by kencu):

 `lilypond-devel` is forced to build with `gcc` as apparently `clang` won't
 work, therefore it can't build against `libc++`. It looks like `lilypond`
 doesn't have this issue, though, so perhaps you might find that acceptable
 for now.

 I guess `lilypond-devel` will have to be examined to see if it's safe to
 put a c++ standard lib override in the Portfile for this specific port.
