I changed lines 637 and 653 of compilers.m4 as you suggested (libc++ instead of libstdc++).

My code runs fine (I’m on Mavericks with latests clang). 

As opposite to the previous build make check now get suck at dual_test. 

The other tests runs fine.  

Thanks everybody for help! 

As Vijay pointed out I thinks this is the way to go since it allows to use c++11.

Thanks again.

Bests.
