Check out xdelta:
http://www.xcf.berkeley.edu/~jmacd/xdelta.html

That page says a lot about xdelta, but in its simplest form it's just a
commandline utility that works like diff/patch but can handle binary
files.  The guts are broken out into libxdelta as well, and I found perl
bindings for that with a google search (not on CPAN).
