I have a Bitnami Ubuntu server currently running apache and modpagespeed but need to upgrade. I tried installing the latest mod-pagespeed-stable_current_amd64.deb but got an error apache isn't installed and was missing a library. Upgraded to Ubuntu 14.04.6 and that resolved the library issue but recognizing apache still caused me a problem. dpkg doesn't see apache. It's installed in /opt/binami/apache.

So, I tried following https://www.modpagespeed.com/doc/build_mod_pagespeed_from_source instructions, but it won't compile. It complains of a missing file. Any chance you might have that file? I searched your source and didn't see it. APR_Pools.h

This is the error.
pagespeed/system/apr_mem_cache.cc:25:34: fatal error: apr_pools.h: No such file or directory
#include "apr_pools.h" // NOLINT

compilation terminated.
