title: iPhone 4 iOS5 Core Plot and ARC error:"The current deployment target does not support weak references"
body: <p>I've converted my project to iOS 5 and enabled ARC. Now I need to integrate core plot with the project. When I try to instantiate a sample controller included with the Core Plot, I get about 20 errors as follows:</p>
  
  <blockquote>
    <p>The current deployment target does not support automated __weak references</p>
  </blockquote>
  
  <p>I've explicitly said <strong><code>fno-objc-arc</code></strong> next to the controller's name in the build settings. </p>
  
  <p>What else do I need to run core plot with ARC enabled?</p>
  
  <p>Thank you!</p>
