Your reported zlib version has known security problems. It's possible your
vendor has fixed these problems without changing the version number. If you
are sure this is the case, you can disable the check by running
"./configure --without-zlib-version-check".
If you are in doubt, upgrade zlib to version 1.2.3 or greater.
See http://www.gzip.org/zlib/ for details.])
