Tobias' method of offering statically built compilers is safer, in the 
sense that it doesn't assume that certain libraries are present on the 
user's system.

Unfortunately, I do not know where libmpfr.so.1 is on Red Hat Enterprise 
systems (and more importantly, I do not know whether it is up to date - 
gfortran requires a specific version or above; I use Debian Testing's 
MPFR version 2.4.1-p2.

Hope this helps,
