I have a linode VPS, running openSUSE 12.1 (A little outdated, but stable). I have installed the RPMS for mod_pagespeed. mod_pagespeed.conf has "ModPagespeed on".

Restarting apache fails after enabling pagespeed. the errors are not very helpful.

li361-39:/usr/lib64/apache2 # a2enmod pagespeed
li361-39:/usr/lib64/apache2 # service apache2 restart

redirecting to systemctl
Job failed. See system logs and 'systemctl status' for details.
li361-39:/usr/lib64/apache2 # systemctl status apache2.service

li361-39:/usr/lib64/apache2 # service apache2 restart

li361-39:/usr/lib64/apache2 #

And the error log (/var/log/apache2/error_log) is useless as well.

I've tried looking for other logs and checking the mod_pagespeed.conf against posts claiming it works and nothing is striking as wrong. Any Ideas?
