puppetmaster-passenger does not install cleanly from scrach

[Glenn Aaldering]

When installing puppetmaster-passenger the install will not finish without errors. After doing some research the problem is because apache2 mod_headers is not enabled.

Output from install:

To activate the new configuration, you need to run:
  service apache2 reload
Syntax error on line 29 of /etc/apache2/sites-enabled/puppetmaster:
Invalid command 'RequestHeader', perhaps misspelled or defined by a module not included in the server configuration
Action 'configtest' failed.
The Apache error log may have more information.
   ...fail!

The fix:

a2enmod headers
/etc/init.d/apache2 restart

It seems that only the SSL module is enabled through this install, but it needs mod_headers too in order to run
