Crazy code on my site after installing some plugins

When I finished installing several of the WPMU BuddyPress Plugins, the following code appears on my site header. Can you tell me what all this means and what I need to do to remove it?

I did not activate any of the plugins and I am not sure which one or ones are causing this.

if you need to see it for yourself, check edberry.com
