mod_pagespeed : install earlier version compatible with libc6 2.13 (Debian Wheezy)

[[ IMPORTANT UPDATE: If you're serving secure HTTPS pages on your server (we are not), the below won't be an acceptable solution for you due to a High Severity security issue that was resolved in mod_pagespeed release 1.11.33.2 , but if you're sticking with HTTP, it will work just fine. - read more on this here and at developers.google.com/speed/pagespeed/module/release_notes#release_1.11.33.2-beta ]]

I dug around and came up with a solution:

It turns out there's a mod_pagespeed amd64 deb package archive at pkgs.org :

https://pkgs.org/debian-ubuntu/google-mod_pagespeed-amd64/

Instead of 1.11.33.0-beta which was available and in theory should have worked, I had to go back to 1.9.32.14 because anything newer still threw this error during dpkg:

dpkg: dependency problems prevent configuration of mod-pagespeed-beta:
mod-pagespeed-beta depends on libc6 (>= 2.14); however:
Version of libc6:amd64 on system is 2.13-38+deb7u7.

So by trial and error, eventually I ran this and it worked :)

sudo wget "http://dl.google.com/linux/mod-pagespeed/deb/pool/main/m/mod-pagespeed-stable/mod-pagespeed-stable_1.9.32.14-r0_amd64.deb"
sudo dpkg -i mod-pagespeed-stable_1.9.32.14-r0_amd64.deb
sudo apt-get -f install
sudo service apache2 restart

I now have mod_pagespeed running on Debian Wheezy. I know it's a deprecated version, but still ...
