This is certainly a Frequently Asked Question, but it doesn't appear to be
in the FAQ.  Many distributions stash an old copy of libz in
/usr/X11R6/lib.  The result of this is that configure finds the new
version, but make ends up linking against the old version, producing the
errors you list.  The solution is to remove all old versions of libz, so
that you are left with only the libz from zlib version 1.1.2.  Then rerun
ldconfig.

This should not cause problems with programs linked against the old libz,
all the ones I've tried or heard about will happily run with the newer
libz.
