Hi,
So far, Apple/clang-500 has not been tested by the CGAL project, but I doubt 
there would be any problem.

The linkage error is:
> Undefined symbols for architecture x86_64:
>  "CGAL::is_ascii(std::__1::basic_ios<char, std::__1::char_traits<char> 
> >&)", 
> referenced from:

It means that the CGAL libraries symbols are not found.

Can you run please `make VERBOSE=1` and copy to pastebin?

My guess is that the CGAL libraries are linked, but for some reason are 
binary 
incompatible. Have you also compiled the CGAL libraries with the same 
compiler? Or do they come from something like "macports", or "brew"? Or did 
you compile them with a different version of the compiler (for example before 
you upgraded to Darwin 13)?
