title: Universal preference pane is forced to launch on 32-bit
body: <p>I'm building a Preference Pane for an application, it's Universal (PPC/32-bit/64-bit) but when I install it on the System Preferences, i'm forced to run it on 32-bit. Any idea why and how to solve it?</p>
  
  <p>if i run file FILE_PATH i get:</p>
  
  <pre><code>FILE_PATH: Mach-O universal binary with 3 architectures
  FILE_PATH (for architecture x86_64):    Mach-O 64-bit bundle x86_64
  FILE_PATH (for architecture i386):  Mach-O bundle i386
  FILE_PATH (for architecture ppc7400):   Mach-O bundle ppc
  </code></pre>
