Comment (by chrpepper):

 I've added a line "configure.cxxflags-append -std=c++11" to the Portfile.
 This lets it compile for my 10.6.8 box (it could cause problems for newer
 OS X versions), but at linking there are undefined symbols like
 "std::__throw_out_of_range_fmt(char const*, ...)" ,
 "std::__throw_bad_function_call()"   etc.
 So, some linker flag is needed, too...
