I had a similar problem. For me, the following worked.
Use this configure command:

CXXFLAGS="-std=c++11" configure [all your configure options] -c++11

This forces the build system to use C++11, because by default C++98 is 
used IIRC.
There is a compiler bug for c++98 (has_feature macros are defined but 
the c++11 classes are not avaible) and I found a bugreport about it (for 
gentoo), but the gcc developers said it's a downstream bug. Unfortunally 
I can't find the bug report anymore :/

I hope this helps, David
