=> I am afraid this libz dependency is very indirect, perhaps from
a crypto library. config.status should say more but it should not be
enough a problem to justify an effort to solve it.

=> a bit more surprising. BTW what is the version of lease cmds hook code?

=> fully Debian specific (and internal). IMHO this should be ignored.

PS: I noted we should look at the Debian tool which detects useless
dependencies.
