title: MonoMac projects cannot compile: ibtool exited with code 1 - Can't run /Developer/usr/bin/ibtool (no such file)
body: <p>I'm moving my first steps in MonoMac. </p>
  
  <p>But I stopped right at the beginning due to some configuration error. I've created a new ManoMac project in MonoDevelop, and then tried some other sample MonoMac xamarin projects from GitHub, but I always get this error compiling:</p>
  
  <blockquote>
    <p>Error: Can't run /Developer/usr/bin/ibtool (no such file).
    ibtool exited with code 1</p>
  </blockquote>
  
  <p>My configuration:</p>
  
  <p>Operating System:
      Mac OS X 10.7.3
  MonoDevelop 2.8.6.5
  Runtime:
      Mono 2.10.8 (tarball Mon Dec 19 17:43:18 EST 2011)
      GTK 2.24.5
      GTK# (2.12.0.0)
  Mono for Android not installed
  Apple Developer Tools:
       Xcode 4.3.1 (1176)
       Build 4E1019
  Monotouch: 5.2.5
  MonoDevelop.MonoMac 2.6.0.0</p>
  
  <p>All my Monotouch projects compile fine, and I have no problem with the last XCode (following the Xamarin guidelines I successfully upgraded XCode and moved it from the obsolete Developer folder to the Application folder, and downloaded the updated developer command line tools from apple).</p>
  
  <p>I've tried reinstalling MonoDevelop, but with no success. I always get: "Error: ibtool returned error code 1."</p>
  
  <p>Any help is appreciated.</p>
