No laughter. I've heard older and odder problems with RPM.

Now I'm laughing ;-)

The issue is a bit deeper than just changing configuration since
there's a whole installer behavior of RPM itself that is being tracked.

The reliable fix is to to just add a patch to rpm- to not
add the tracking dependency.

You can try (its very much not the right thing to do, but you are
already pretty desperate for a fix if patching digests) adding
	Provides: rpmlib(PartialHardlinkSets)
in the same package to stub-out the Requires:. I won't bore you
with the details of why its not the right thing to do. But if
you can mask the Requires: by adding a Provides: you will
likely be able to install.

Another approach to masking the Requires: would be to patch
the Provides: into rpm-4.0.2.

But if you can't rebuild either version of RPM, well, its rather
hard to retrofit forward compatibility without changing code.
