Comment (by RJVB):

 Yep, it was moved from experimental to in 9.0.0 .

 > using macports-libcxx, you have a “two libc++-versions-at-once" issue.

 Either you missed what I wrote about what is actually loaded into memory
 (and the fact of setting the dylib `current_version` info), or you have
 proof that I don't. Do you?

 FWIW, libcxx 5 also builds with cmake. I've modified my version of the
 port so it uses that method when possible, which makes it a lot easier to
 patch the build. It complexifies the Portfile but IMHO that's worth it.
