Unable to load the requested class: message

I'm using 1.7.2 Straight out of the box!
This is in my autoload:

Code:

$autoload['libraries'] = array('database','session','message');

beyond that, nothing.

Here's the link to my question about the subject in another section of the forum: viewthread/167144

Anything else I can add?
