You should do it *before* the activation hook. I have a bootstrap file 
that contains my plugin's header and license information, and it 
performs checks to make sure everything is in place. If the requirements 
are met, it includes and instantiates my plugin's main controller class.

If an error is found (PHP version too old, missing lib, etc.), it 
displays a standard admin error message via the add_action hook.

Does that make sense?
