Comment (by kencu):

 Homebrew just last week spun the libunwind that is built with LLVM into a
 subdir, exactly as we just did with libc++, to avoid opportunistic
 linking:

 https://github.com/Homebrew/homebrew-
 core/commit/c2b0a53df5735b2433942ec504d4fb2abcdcbf2a


 The current libunwind port in MacPorts needs to be modified to install
 it's software only on 10.6 and less, and be a no-op dummy port on newer
 systems. I would have done this already, but a ton of things will break
 and have to be revbumped and I wasn't sure we were quite up for that
 project yet. But we might as well be, as it will have to be done anyway.

 There is a ticket somewhere to install the current libunwind port into a
 subdir, but this will break many things on 10.6 and less and seems
 needless to me now that a current libunwind is coming in with clang-N
 installation.
