I had the same problem. This was caused by /usr/X11R6/lib/libz.a.
If you install XFree-3.3.2 from sources, you will get /usr/X11R6/libz.a.
Since -L/usr/X11R6/lib is added to LDFLAGS, a build attempt will end up
trying to link against zlib in /usr/X11R6/lib instead of using newer version
installed, on my machine, in /usr/lib.

I circumvent this problem simply by setting LDFLAGS=-L/usr/lib before
invoking ./autogen.sh to enforce the linker to look for libraries in
/usr/lib first.

So if you are using Bash, following line should hopefully help you link
against your newer zlib, if you have it installed in /usr/lib. Otherwise
replace /usr/lib with a directory where you have zlib installed.

  # LDFLAGS=-L/usr/lib ./autogen.sh
