mod_pagespeed in directadmin (debian)

[rpr]

Hi,

What is the correct way to install mod_pagespeed in apache2?
Because every tutorial I read said this:

wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-stable_current_amd64.deb
dpkg -i mod-pagespeed-stable_current_amd64.deb

but that results in:

dpkg -i mod-pagespeed-stable_current_amd64.deb
Selecting previously unselected package mod-pagespeed-stable.
(Reading database ... 39715 files and directories currently installed.)
Unpacking mod-pagespeed-stable (from mod-pagespeed-stable_current_amd64.deb) ...
dpkg: dependency problems prevent configuration of mod-pagespeed-stable:
 mod-pagespeed-stable depends on apache2.2-common | apache2-api-20120211; howeve                                                                                                                                                             r:
  Package apache2.2-common is not installed.
  Package apache2-api-20120211 is not installed.

dpkg: error processing mod-pagespeed-stable (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 mod-pagespeed-stable

or is it save to install apache2.2-common?
