environment modules for gcc/gfortran?

[Katherine Holcomb]

I don't have an opinion on version; 4.7 was just the latest official 
version of which I'm aware.

We run the equivalent of Centos 5.4 on our cluster and there is an rpm 
for gcc 4.4, but it installs under the names gcc44/gfortran44 which 
makes it less convenient for most users.  I wasn't able to get my module 
script to alias gcc44 to gcc or gfortran44 to gfortran, though I haven't 
put much effort into it.  Version 4.4 gfortran still lacks many 
important new features that are well supported even in 4.6 (for 
instance, 4.6.2 will compile and run a tiny little "blackjack" program I 
wrote with type-bound procedures that ICEs Intel ifort 12.1.2).  
Unfortunately I don't have any advice on building 4.6 or later on Centos 
5.4 since I've never tried it.
