How can I remove the "Install WPMU Dev Dashboard" from my wordpress?

I'm getting really annoyed. There is a message at the top of my wordpress that says "Easily get updates, support, and one-click WPMU DEV plugin/theme installations right from in your dashboard - install the free WPMU DEV Dashboard plugin. " I don't want to install the dashboard on this site, I just want to use their plugin. How can I make this go away?
