if you ran jk_update -v (verbose) would that tell you that libz was 
checked for updates? (probably too late to test now). This could be a 
bug in jailkit, so if you could help to find what was going on..

possibly it was used by another binary that is no longer in your jail?

possibly you have a binary in your jail right now that does not function 
anymore. The other possibility is that you previously had a binary in 
your jail that needed libz but the binary is not there anymore or it 
doesn't need libz anymore.
