Wow, this really sucks. It means that on Mountain Lion and earlier, cmake now depends on clang-5.0, clang-4.0, clang-3.9, clang-3.8, and clang-3.7, and on Lion and earlier, also clang-3.4. It also says all compilers are blacklisted so I'm not sure if it builds. Judging by the fact that binary packages were only produced for Mavericks and later, I'm guessing it does not build on earlier systems.

cmake is in the dependency chain of the ports needed for the buildbot worker infrastructure, which I'm just in the process of updating and discovering this problem. Not to mention lots of other ports that heretofore built successfully with libstdc++. Assuming cmake 3.9.5 does not build on systems with libstdc++, maybe you could have the port drop back to cmake 3.9.4 on those systems.

Actually, I can't find the "The C++ compiler does not support C++11" message in 3.9.5. Are you sure it requires C++11? If it does not, please revert the above commit.
