Applied your patch (replacing -v with --version and changing the ver_match
line and it is happily building having found g77

I downloaded the latest atlast and ran the the make. Instead of taking the
default vaules for the compilers, I replaced -64 with -n32. Same thing
with LAPACK, copy the correct make.inc and replaced the -64 with -n32

True. Importing Numeric (20.3, or 21.0) does not produce incorrect
results.  It is specific to scipy.

I compile apps on various platforms (Solaris 2.6/8, IRIX 6.5, HPUX, Redhat
Linux, AIX 4.x, and soon on our bazillion dollar IA64 Linux cluster). I
use gcc for everything if possible. Not quite the performance as some of
the native compilers, but it saves me lots of headaches.

ok.. during all of that I finally got down to the next error. I fixed this
by going to g77 from gcc-3.0.4

So the beast is compiled. I'll see if I can run it and do some testing.
