[PyQt] Problem freezing a Sqlite based PyQT app

I actually had nothing but problems with PyInstaller. In my instance, I 
am using Twisted + PyQt4 in my app, so I could never even get it to run 
while frozen. Not to mention it seems to want to pickup every dll in my 
system to package it into my app (like kernel32.dll).

You can manually copy the Qt plugins folder, since you should only need 
to do this once unless you delete the dist folder each build (that gets 
annoying quick). I know theres no support for implicit dependencies, but 
you can explicitly define them in the setup script (or you can use 
something like Gui2Exe).
