I guess I am going to have to reinstall Qt 4.1.4 on my system. At this point, I have a couple of questions:

1. To uninstall Qt, is it enough to delete the folder Qt-4.1.4? Is a better way to do that? Under Windows there is a utility "uninstall Qt..." but I have not found it on Mac...

2. 55 GB for static, that's a lot. Is the static option essential for a Mac application?

Thanks to patrik08 for the note.
