I regularly build with zlib-ng, unfortunately it requires patching the zlib-ng files to enable zlib compatibility mode as nginx doesn't seem to have a way to pass options to configure.
Edit "configure" in the zlib-ng directory and change the line compat=0 to compat=1. Then specify --with-zlib=/path/to/zlib-ng in your nginx configure and you should be set. Be aware that the memory requirements of zlib-ng have changed since support for it was added to nginx, so you will see a lot of "gzip filter failed to use preallocated memory" alerts in your log file when using zlib-ng.
