Comment (by kencu):

 Apple's `/usr/bin/clang` will restrict you to `libstdc++` with a
 deployment target of 10.6 or earlier (because that system doesn't natively
 have libc++ installed).

 macPorts-installed clangs don't have this restriction.

 So  if you're building with `libc++`, either the `-mmacosx-version-
 min=10.5` will have to be changed to `10.7` or greater, or you'll need to
 use a MacPorts-installed clang
