title: Getting Error: Framework 'Mono / .NET 4.0' not installed. In MonoDevelop / Mac on a new project
body: <p>I have installed Mono 2.10.8 (that should have .NET 4 support) and MonoDevelop 2.8.6.4 on Mac OS X 10.7.3.</p>
  
  <p>I created a new project, but now the IDE displays this error: <code>Error: Framework 'Mono / .NET 4.0' not installed. (Project name)</code>.</p>
  
  <p>What do I need to do in order to be able to compile the project?</p>
