Yes.
What version of OS X? What version of gcc and g77?

How does it fail?
Fink installs its stuff in a non-standard directory (/sw) so you'll 
have to explicitly point configure to the readline.
Fink FAQ (Q6.4): http://fink.sourceforge.net/faq/usage-general.php

g77 installed by fink used to (I don't use fink) have a problem which 
could be corrected by setting FFLAGS = -lg2c

IIRC, this was a problem with octave 2.1.40 in fink.
The package was updated because of this, and the fink page lists 2.1.46 
as the current version in both stable and unstable branches.
http://fink.sourceforge.net/pdb/package.php/octave

Have you updated the package descriptions?
What does "fink list octave" give you?
http://fink.sourceforge.net/doc/bundled/usage.php

Note that the above refers to fink source installs, I have no idea what 
so ever what a binary package would give you.

These are questions for the fink mailing lists:
http://fink.sourceforge.net/lists/index.php

If you want to contact the maintainer of fink's octave package you'll 
find the email address by issuing "fink info octave"

> (c) tell me how to get this to build

You need:
--- Working gcc and g77 of the following (or newer) versions

% gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.1/specs
Thread model: posix
Apple Computer, Inc. GCC version 1175, based on gcc version 3.1 
20020420 (prerelease)

Get it from http://developer.apple.com

% g77 -v
Reading specs from 
/usr/local/lib/gcc-lib/powerpc-apple-darwin6.1/3.1/specs
Configured with: ../gcc3-1151/configure --enable-pfe --disable-nls 
--enable-threads=posix --enable-languages=f77
Thread model: posix
Apple Computer, Inc. GCC version 1151, based on gcc version 3.1 
20020420 (prerelease)

Get g77 3.1 from fink or (precompiled) 
http://gravity.psu.edu/~khanna/hpc.html

--- readline (which you seem to have)

--- teTeX from fink or some other source (I'm not sure if this is an 
absolute requirement)

Follow these instructions (from the octave wiki 
http://www.gnufans.net/octave.pl  which is currently down)
===============================================================
1)  Get octave-2.1.48.tar.gz from http://www.octave.org/download.html

2)  Make sure you have the following installed: Dec2002 (or later) 
DevTools, a working Fortran compiler, readline, and texinfo or tetex.

3)  Unpack it and run './configure' _without_ arguments unless you know 
exactly what you are doing

4)  Edit config.h so that the line:

    /* #undef HAVE_DYLD_API */

instead reads:

    #define HAVE_DYLD_API 1

5) run 'make' followed by 'sudo make install'

6) Test the setup by running 'mkoctfile hello.cc' in octave's examples 
directory.
You should get a file hello.oct that can be run in octave
