This is typical on RedHat 4 installations. I think it goes away with RedHat
5. Basically you can install gfortran which is based on gcc4 and also
install gcc4 but since the whole OS is based on gcc 3.4.6 it installs gcc
with the suffix 4 on everything. Thus in this combination one has to specify
gcc4 in place of gcc for the C compiler.

Yes. If I edit config.h and change gcc to gcc4 then all is good. The issue
is that there is no gfortran4 so the code happily installs gfortran v4 as
the default fortran compiler while leaving gcc defaulted at 3.4.6.

This is because I only used to ever use Intel compilers but I figured I
should test the gnu options as well.
All the best
