I did indeed make it work. The (only) reason I didn't check it in was
because there were some collisions between freebsd's older zlib which
ppp depends on and the one in the solaris layer. Both bz and I were
kind of busy at the time.

I think this can be done without much work, (re)work out the dependencies.
