On FreeBSD we have a similar situation.  libc++ can work, but won't be part of the base system's default install until 9.2 (which should be soon, since 9.1 was massively delayed).  Currently, I don't think the build logic for building libc++ as part of the LLVM build will correctly detect the libcxxrt that we have in the base system.

It would be a shame to make development difficult on the two platforms that have switched to clang as the default compiler...
