iPhone Debugger Message -- Weird

I have an iPhone app that I've been working on and have recently upgraded my version of XCode. Since the upgrade, I can build and debug in the iPhone Simulator just fine, but when I try to debug on an attached device I get the following messages:

looks like there was a problem linking to your frameworks library. try and remove the references and relink them. FYI - do not copy into project as that can cause other problems.
