Problem with g77

[dgwatson@kent.edu]

I've been attempting to compile some fortran code for a fairly important
project, and have been having trouble.  The problem seems to be that there
is no libU77, libF77, or libI77, which is a problem - because the program
needs the functions date_and_time (or something like that - I'm not the
fortran guy, I just admin this box :).  I did an apt-get source g77, and 
dpkg-buildpackage fails - it gives me this error:

--------------------------

I did a locate (I tried building on monday, so updatedb has had a chance to
run), and got this:

penguin:/usr/local/src/gcc-2.95.2# locate gc.h
/usr/local/src/gcc-2.95.2/src/texinfo/info/gc.h
/usr/src/kernel-headers-2.0.36/include/net/gc.h

But neither of those makes much sense.  I could not find a gc_typed.h
anywhere.  Am I doing something stupid? Is there a fortran package I need to
install?  Please help! People are asking to use this program, and I can't
get it to work....
