An item with the same key has already been added.

I installed the latest WSP Builder extensions on a virtual with Windows 2003 Server (32bit).  I have Visual Studio 2008 and MOSS Enterprise Edition installed on the virtual as well.  When I create and deploy any project with the extensions, I get a SharePoint error that states "An item with the same key has already been added."  I have changed the PublicKeyToken and the ID of the feature or webpart in the project.  Is there a step that I am missing in the process of creating and deploying a project with WSP Builder?
