Ok. Dunno why is not detected c++ at configure time. I'm not familiar 
with clang as C++ compiler, especially installed symbolic links.
Please check configure output and then config.log to find why 
detection(tests) for C++ compiler fail. Also check detection of C complier.
For instance autoconf macro should search for availability of g++ or c++ 
or cxx or CC and etc as C++ compiler commands.
If clang C++ is not in list detection fail.

If clang is default OS compiler is expected symbolic link c++ to clang++ 
or similar. May be some OS setup commands could set such links.


Remark:
At end ./configure --help outputs environment variables .
Those variables could be used to tune build process.
For instance CXX=my-c++ ./configure ... could be used to change C++ 
compiler.
