I would better wait for the proper version that depends of Qt4.7 that comes with PR1.3.
It bothers me only in the way I have to download experimental version of what I already have native. You know, it might not screw up the system to have 2 versions of Qt4.7 but there can be a little bit of a mess. I'd prefer to avoid it.

And thanks for replies, good to know we aren't forgotten=)
