If the only thing included in hslibs is a 3BSD-style interface then we
have no problem, the user of the software links against the version of
libjudy installed on the system.

I am the original author of the HsJudy bindings which I implemented for
building very fast free variable sets in jhc. I considered making a
stand-alone version that included the judy source, but decided it would
be much nicer to just link against the libjudy installed on the system
as it is a generally very useful library.
