Look and see how the control panel is added ... it's somewhere in there (this is actually the My Account page for users). Also go to a class, click on "control panel", find the file you land in (not control panel - something like one community admin!) and see where it's added to the navbar. Grep should find this for you.
BTW those procs really suck... :) I hope to replace them with proper templates at some point (the rewritten portals package does in its OpenACS integration code so it should be possible eventually).
