It looks like your Fortran compiler installation is borked.  Have you tested 
with the same test program that configure used?

       program main

       end

Put that in a simple "conftest.f" file, and try the same invocation line that 
configure used:

    /usr/local/bin/gfortran -o conftest    conftest.f

Does that work?

If that works and does not yield the same error that configure saw, then 
perhaps there is some environment variable(s) that are/were present when you 
run configure that are not present when you try the test manually...?
