I also use autoconf and friends. I use the following incantation:
# F90 dependency tracking
f90_dep.mak:    $(srcdir)/*.F90 $(srcdir)/*.f
                $(top_srcdir)/scripts/f90_dependencies.py -o $@ $^

-include f90_dep.mak
This will automatically update the list of dependencies if any of the
*.F90 or *.f files has changed.
Ah, would be nice to get proper fortran support in autoconf. There is a
fairly comprehensively patched autoconf/automake system out there. It
would be nice if those changes got merged into the main autotools sets.
Ah well, once can hope.
