Comment:

 The only similarity I see with #27113 is that both there and here a "cp"
 usage message is printed, because the dylib didn't get built. In #27113 we
 have not yet figured out why. In your case, the relevant error in your log
 seems to be:

 {{{
 dyld: shared cached file was build against a different libSystem.dylib,
 ignoring cache
 }}}

 This is a new error message to me. As in #27113 there is lots of "Skipping
 completed" in your log, which means this was not a clean build. It sounds
 almost like you began building zlib, then upgraded Mac OS X (or migrated
 MacPorts to a Mac with a different version of Mac OS X), then tried to
 continue the build; this certainly won't work. Please clean and try again.
 If that fails again, attach the complete main.log.

 {{{
 sudo port clean zlib
 sudo port install zlib
 }}}

 #27113 is possibly a duplicate of #26224; please see also if any of the
 hypotheses listed there fit your case.
