Comment (by rmottola):

 as an added note.... since there is a line that says "avoid circular
 dependency" cmake-clang.
 I cannot compile cmake with clang 3.7 on 10.5!

 on x86, I get:



 {{{
 Error when bootstrapping CMake:
 Cannot find a C++ compiler that supports both C++11 and the specified C++
 flags.
 Please specify one using environment variable CXX.
 The C++ flags are "-pipe -Os -fpermissive -D_GLIBCXX_USE_CXX11_ABI=0
 -stdlib=macports-libstdc++ -arch x86_64".
 They can be changed using the environment variable CXXFLAGS.
 See cmake_bootstrap.log for compilers attempted.
 }}}


 and on x86_64 I get exactly the opposite, where arch is 386.

 Compiling with gcc 6.5 fails too! so.... while I can upgrade with clang
 5.0, I forsee an issue here for fresh installs.
