Something similar to that should work for most of the fortran using
spells. It should only be done if there's no g77 installed though, so it
also works in test grimoire.

Just symlinking it could lead to weird problems as gfortran is _not_
g77. It's a completely new fortran compiler written from scratch for gcc
4.0 that has some additional features and some features available in g77
missing. We should make our fortran using spells use gfortran
explicitly on gcc4 systems to test if everything works as expected.
For the dependency issue I'd suggest a dummy 'fortran' spell for test
grimoire depending on g77 so spells just depend on fortran.
With gcc 4.0.0 gfortran couldn't build all spells we have using fortran,
but I think the releveant bugs have been fixed in 4.0.1 and 4.0.2.
