I think that comes from the following piece of code.  I assume that
you initialize withval to maybe at the beginning of your configure.in
so it gets set to that if no option was given.

dnl if withval not no or and not yes
if test "$withval" != "no" -a "$withval" != "yes"; then
    Z_DIR=$withval
    CPPFLAGS="${CPPFLAGS} -I$withval/include"
    LDFLAGS="${LDFLAGS} -L$withval/lib"
fi

dnl if withval is maybe
if test "$withval" = "maybe"; then
    withval="yes"
    Z_DIR=""
    CPPFLAGS="${CPPFLAGS}"
    LDFLAGS="${LDFLAGS}"
fi

Can you show us the compile line where it fails to find libz at build
time?
