Forget this post. I was calling to bjam as follows

bjam toolset=gcc-4.8x

but in my user-config file I configured

using darwin : 4.8.0x : /usr/gcc-4.8/bin/g++-4.8 : <lnkflags>-lssp 
<cxxflags>-fstack-protector-all <cxxflags>-std="c++11" ;

Unfortunately bjam toke the default gcc which doesn't runs in c++11 mode 
without any explicit ERROR :(

using darwin ;

Best,
Vicente
