Aegir::extras does not work with Aegir::dev

I'm not really sure why this is, but Aegir::extras does not work if you install Aegir via the aegir::dev class. I was using the normal 'aegir' class before, and it worked fine, but when I switched to using 'aegir::dev', I started getting the following errors...

Puppet error:

I'm not sure what's different here... the class Provision_Service does exist... but it's not getting picked up for some reason.
