Comment (by ryandesign):

 This ticket is only about bundling libc++ with MacPorts on 10.6. Our
 current goal is to switch 10.6-10.8 to libc++. This is easy on 10.7-10.8
 because they include libc++, and hard on 10.6 because it does not.
 Bundling libc++ with MacPorts on 10.6 makes it easier.

 I have not given specific thought to how it would be accomplished, other
 than what I've already said above. We could either do it in the Makefile
 as I suggested above, or we could have separate implementations for the
 installer pkg and for installing from source.

 As far as I remember, libc++ doesn't work as well, or at all without some
 patching that Ken mentioned somewhere previously, on 10.5. clang doesn't
 work on 10.5 on PowerPC. I don't know/remember if libc++ can be used with
 gcc. Since we are not currently planning on switching 10.5 to libc++, we
 don't need to consider how to do this now.
