Hi, I agree that the integration of the 4.6 beta packages is a bit hackish, and I will have a deeper look into the details. But it was just meant to test already the 4.6 packages, so to say a preview within a preview. Sorry for the inconvenience. But be aware that soon there will be PR 1.2 with Qt 4.6 integrated, which means as well that you will get a newer version of MADDE, which compiles against that rootstrap. That will make those things a lot easier and cleaner.
