Installation issue

I have a couple of issues, following the installation instructions on the documentation page, as I'm being asked to enable things I can't see:

> Enable Activity and enable at least Activity history, Buddylist activity, Comment activity, Node Activity

I have enabled "Activity" in modules. I can't see any of the other items listed here in modules. Are these other modules that need to be installed? If so, why are they not listed as dependencies for Activity?

> Now come to admin/user/access and select the check boxes for 'view own activity' and 'view public activity' for authenticated users (and any other roles you may have in your site)

"View own activity" and "View public activity" are not listed in Permissions. I do have "administer activity", "delete own activity" and "manage own activity settings".

Any ideas?
