Yes, this is a pain. We've heard it before about openlinux, but didn't
seem to find a solution (or did we?). Some ideas:
Would it work to use f2c as your fortran compiler instead (configure
--with-f2c)?
Are there any *f2c.* files lurking around? I haven't looked at egcs
sources since egcs-2.90.23, but it seems that they actually build
f2c.h and libf2c.a and RedHat renames them g2c to avoid name clashes
with the "real" f2c.
If you have the install CD handy, perhaps try something like
find /path/to/RPMS/ -name *.rpm -exec sh -c "rpm -qlp {} | grep
[fg]2c" \; -print
to see what package contains files named something with f2c or g2c.
There was a note from Jack Fenner on how to extract the libg2c.a file
from the RedHat RPM with rpm2cpio which seemed to work for him. He
ended his not with a request for instruction on how to use the
program, so I'm not sure it got tested very thoroughly... Anyways,
here's what he did:

I then encountered the linking same problem as you describe below. The
error message is saying that the compiler can't find the libg2c library,
which is its runtime library. Apparently the g77 supplied by Caldera is
missing this important piece. I downloaded egcs-1.1.2-12.i386.rpm from
the Red Hat web site, then did the following to extract and install libg2c:
1) rpm2cpio < egcs-1.1.2-12.i386.rpm > egcs-1.1.2-12.cpio
2) cpio -irv \*libg2c.a < egcs-1.1.2-12.cpio
- when prompted to rename it, I entered libg2c.a. This created the
libg2c archive in my current directory.
3) mv libg2c.a /usr/lib/gcc-lib/i386-linux/egcs-2.91.66
