Just grabbed the package... Makefile uses syntax not accepted by GNU make. Uses that <err.h> header which we don't have. Took a look at the code... Owww! My eyes!

It's only got to P(alphabetically), but that is still a lot of packages. So far, only one difference: The fortune bz2 has a few KB of nulls appended to the bz2 data, which of course get stripped by the de/re-compress. There are only 2 packages left in the distro using gzip-compression (crypt and irc) - we can probably get those recompressed as bzip2, if it turns out to be an issue.
