I'm willing to bet that you have g77 installed from gcc-3.4.6 and gfortran
from gcc-4.3.0.  ./configure found g77 first and used it to figure out the
fortran link libraries, which will not work with a main compiled with

The fix should be to simply make sure that the underlying fortran compiler
used is gfortran, whether that be through your mpif77 configuration or
trilinos' ./configure...
