title: .app file appears in red (missing) in new projects with Xcode 4
body: <p>Every time I create an Xcode 4 project (iPhone app, cocoa library...) the .app file or the .a file under Products group appears in red (is missing). </p>
  
  <p>Even if I build the project the file stills in red.</p>
  
  <p>All my settings are default.</p>
