clang-3.9 will not build

[kwodzicki]

I have been trying to install some packages that depend on clang-3.9 but it will not build. I have tried uninstalling all my clang versions, cleaning them, and re-installing and clang-3.9 fails every time. clang-3.7 & clang-3.8 build fine. Below is the output from the port command and I have attached the log file. It appears it is an issue with the libc++ and libstdc++ libraries, but I am not sure how to fix the problem as other forms have not be helpful to me.
