That version of clang does not use -stdlib=libc++ by default. Instead, it 
uses 
libstd++ (the STL from GNU/g++).

Probably the compilation of Boost using b2 has used the default stdlib 
(libstdc++), and not the libc++ you have used to compile CGAL libraries. That 
way, you get libraries that are binary-incompatible. I suggest you either 
recompile Boost libraries with libc++, or recompile CGAL libraries with 
libstdc++.
