title: Unable to build with Qt on Snow Leopard
body: <p>I installed Qt and tried to build a template project (Qt4 Gui Application) in QtCreator.  I can't figure out why I am getting these errors.</p>
  
  <pre>Running build steps for project SourceControl...
  Configuration unchanged, skipping QMake step.
  Starting: /usr/bin/make -w
