Yes. However, I'll have to worry about overwriting and possibly breaking my build environment with 3.2.2 coming out next Friday (Simon's binary package rather carefully installs gfortran-4.8, but not gfortran, I believe. Won't know about the others until I try them.). So, not on this machine.

I haven't seen evidence that there is a problem with the CRAN binaries of anything and we still need to provide gfortran somehow for people who need to build from source. What we could try is to compile 4.8 on a C2D or cross-compile it for that architecture. I think that the latter is doable, but I don't recall the details (gcc --target ?).
