title: Xcode doesn't seem to execute my scheme's post-action
body: <p>I'm using Xcode (4.6.2) and my target is an external build tool. The auto generated scheme calls that just fine during build.</p>
  
  <p>On RUNNING, I wanted the scheme to execute another shell script. It wasn't intuitive, but I managed it by setting <code>/bin/bash</code> as executable and passing my script as parameter.</p>
  
  <p>The only step left is that I want to execute yet another script AFTER run. And here I thought it'd be easy and just tried to set it as a post-action.</p>
  
  <p>BUT no matter what, I can't get xcode to execute my post-action script.
  No matter what it is. I tried <code>echo hi &gt; /tmp/testfile</code> even...</p>
  
  <p>I need that post-action to do a bit of cleanup.</p>
  
  <hr>
  
  <p>Again in short:</p>
  
  <ol>
  <li>I have a script <code>build_me</code> that is my external build tool</li>
  <li>I have a script <code>run_me</code> that I set my scheme to run</li>
  <li>I have a script <code>cleanup</code> that I <strong>want to</strong> have as run post-action</li>
  </ol>
  
  <p>Can't get Xcode to run my post-action script <em>or any</em>.</p>
