There are two really stupidly simple answers here.

Add Chinook Extras to your Application catalog as mentioned above, and add the Collabora repo from http://www.gronmayer.com/it.

Chinook Extras will serve as a stop-gap until Diablo Extras gets up to speed in a few weeks, and the Collabora repository has the telepathy plugins to allow you to use more services with rtcomm.

Also, calm down.
