GCC 4.7 has been compiled and installed on the ICTS HPC cluster. In order to make use of it execute "module add module-gcc47" from the bash prompt on the HPC headnode and it gets enabled with the correct paths to the various libraries.
We made it available just in case students from CS ask "Why ??" we are not bleeding edge enough :-)
Installation was trival and followed the documentation as per a earlier blog post which I wrote up. It can be found here - Compile / Install / Deploy OpenFOAM 2.0
Enjoy !
