Paul, Katherine, Tom,

the binaries at http://gfortran.com/download/x86_64/
will probably work on RHEL / Centos 5.4 (modulo libgomp), it's worth a try.
See the readme file in the directory. You will find the latest
snapshots of GCC 4.3, 4.4, 4.5, 4.6, 4.7, 4.8 so you can choose
which to take.

Cheers,
Manfred
