I don't want to sound presumptuous, but I can't imagine why they'd refuse
to install a RH-validated package on a RH system, package which was made
exactly for purposes like the one at hand.  C++11 is only becoming more
common and a dependency of many upstream projects.  clang/llvm just
recently started requiring gcc 4.8 too (for full C++11 support),
for example.
