I think Michael Rutter (who (re-)builds for 12.04 and other Ubuntu releases
when I update the Debian package) can create a local backport of zlib.

I somewhat recently started to (entirely locally) build some "backports" via 
https://launchpad.net/~edd/+archive/ubuntu/misc solely so that Travis can use
them as binary.  It's good option to have.
