I can't follow you here - the :uffi feature declares if the foreign
function interface is available for this Lisp implementation or not. It
doesn't have anything to do with the existence or location of a zlib
library.

So if you compile on a system with UFFI support, the resulting delivered
image will include all the #+uffi code. It will locate and load zlib if
it can, or fall back to no compression if that fails.

Or am I completely misunderstanding something here?
