I don't think a binary patch is workable: all it takes is a single local
buildworld and you've got an unpatchable system. Furthermore, I'd
speculate that binary patches would usually be on the same order of size
as the file itself. What *would* work is including the entire new file in
the package. This is what solaris does.

However, there are serious regression-testing and dependency problems with
a scheme like this - i.e. making sure you've included *all* of the
relevant changes.
