apache2 fails to build when configure can't find zlib

[cmconnelly (Claire Connelly)]

During the configure process, configure dies with

checking whether to enable mod_deflate... configure: error: mod_deflate has been requested but can not be built due to prerequisite failures
Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_www_apache2/apache2/work/httpd-2.2.25" && ./configure --prefix=/opt/local/apache2 --with-apr=/opt/local/bin/apr-1-config --with-apr-util=/opt/local/bin/apu-1-config --libdir=/opt/local/lib --with-expat=/opt/local --with-pcre=/opt/local --mandir=/opt/local/share/man --enable-mods-shared=all --enable-authn-alias=shared --enable-ssl --with-ssl=/opt/local --enable-cache --enable-disk_cache --enable-file_cache --enable-mem_cache --enable-deflate --enable-proxy --enable-proxy-connect --enable-proxy-http --enable-proxy-ftp --with-mpm=prefork

The configure script seems to only be looking in /usr and /usr/local for zlib. Adding –with-z=/opt/local allows configure to complete.

What version of OS X and Xcode and clang are you running? May I see the main.log and config.log file? You're the first person to report this problem, as far as I'm aware.

The z lib path should be {$prefix} i think.
