Installation of gcc-4.7 on Fedora 16 still shows gcc-4.6
===

I built and installed gcc-4.7 on Fedora 16 from source. But when i go to the installation directory (/opt/gcc-4.7.0/bin) and query for the version `g++ -v`, i get `gcc version 4.6.3 ...`. I did not use any suffix like `-4.7` during the configuration, so my installed binary is `g++`. Is there any other configuration required post installation?
