With PR1.2 of Nokia N9 : - gcc/g++ were removed; - I can't reinstall then by using "apt-get install build-essential" ou "apt-get install gcc g++", etc. There are dependencies problems between Harmattan SDK beta 3 and MeeGo 1.2 Harmattan PR1.2. I think we need to wait the release of Harmattan SDK beta 4 repository...
