title: RestKit Derived Data Troubles
body: <p>I'm trying to get going with Restkit. I've followed the install instructions here: <a href="https://github.com/RestKit/RestKit/wiki/Installing-RestKit-in-Xcode-4.x" rel="nofollow">https://github.com/RestKit/RestKit/wiki/Installing-RestKit-in-Xcode-4.x</a>  </p>
  
  <p>I'm running Xcode 4.3.2. When I try to run the RKCatalog project, I get an error: clang: error: no such file or directory: '/Users/sparky/Library/Developer/Xcode/DerivedData/RKCatalog-fdohdnazcupmydfaxxedezitkbpl/Build/Products/Debug-iphonesimulator/RestKit/RestKit'</p>
  
  <p>I'm not an Xcode expert. I'm not sure where to go from here. </p>
