You have to worry about including the copyright and license in your software. I've never seen a project do that so I'm not sure how to do it or if MIT is actually usable.
The attribution clause only applies to the licensed code, not derivatives. In practice, all this means is that you can use an unmodified copy of Imba (which contains its own license/attribution language) without issues.
What's not cool is to fork Imba, remove the attribution to the original author and pass it off as your own code.
Nothing you should worry about. MIT is a very permissive license.
