/clang-mp-3.9 -- broken!

     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.4.1
 Keywords:  snowleopard  |       Port:  clang
-------------------------+-------------------
 Trying to migrate to what is described in
 https://www.macports.org/install.php#installing I started to build to
 build the ports. In order build `apple-gcc40 apple-gcc42 clang-4.0` first
 `llvm-4.0` needs to be built. This fails early:
