shared library version binary patch?

[pst at ir.stanford.edu]

I hope someone can help out here -- I'm in somewhat of a jam.

SunOS 4.0.3 / Sun 3

We built a _ton_ of software on a machine that had libc.so.13, rather than
libc.so.12.1 (which would be the proper version for the library with
resolver support).  This software is supposed to be used on hundreds of
machines, so I can't tell everyone to just diddle their shared library
version to match mine.

Is there a crufty way to patch the executable's I've built to request
version 12.1, rather than 13 of a library?  The code in the shared
libraries is the same (it was just named incorrectly),  so I'm not worried
about a true version mismatch.
