I am trying to build a playbook app using the QT libraries recently released by rim.

The app builds and deploys fine if I use the default bar-descriptor.xml, but the bar file is ~80MB in size. I would like to reduce the size. I have tried using a modified bar-descriptor.xml which only includes the needed libraries but I get 

 Failed to load platform plugin "blackberry". Available platforms are: 
 Minimal

The original bar-descriptor.xml file is 

<?xml version="1.0" encoding="utf-8" standalone="no"?>
