My patches in this local fork have been merged upstream, but they have been merged after 0.9.8 and 0.9.9 hasn't been released yet, so we cannot yet switch back to finding libvncserver externally. So I am syncing now with basically what is 0.9.8 + my patches and a few bugfixes. svn path=/trunk/KDE/kdenetwork/krfb/; revision=1258493
