It IS found on my gentoo system:

bash-2.05b$ g77 -fversion
GNU Fortran (GCC) 3.3.5  (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1)
Copyright (C) 2002 Free Software Foundation, Inc.
[snip]

This is where portage puts it:

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

bash-2.05b$ locate g77

[stuff deleted]

/usr/share/gcc-data/sparc-unknown-linux-gnu/3.3.5/man/man1/g77.1.gz
/usr/sparc-unknown-linux-gnu/gcc-bin/3.3.5/g77
/usr/sparc-unknown-linux-gnu/gcc-bin/3.3.5/sparc-unknown-linux-gnu-g77

[more stuff deleted]

bash-2.05b$ locate f771
/usr/lib/gcc-lib/sparc-unknown-linux-gnu/3.3.5/f771

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

As someone else noted you have to set the USE flags to 
include 'f77' or 'g77' and emerge gcc.

But setting USE = f77 did not leave a link or copy of g77 in /usr/bin. 
Hence, the symlink referred to in my message below.

Apparently, Gabriel and I are not the only ones to come up against this. 
There are a number of discussions like this one:

 	http://forums.gentoo.org/viewtopic.php?t=266985

where the solution was to copy or symlink /usr/bin/gcc to /usr/bin/g77.
