I have been heads down busy getting KDE 4.2.4 to build on BeleniX with Gcc 4.4. I recently completed kdebindings and kdebase and had enough to get a KDE4 desktop started. Since I am doing chrooted builds in an alternate boot environment, all I had to do was to reboot into that BE and issue ‘xinit startkde’. Here is a hurried digicam picture after running my first KDE4 desktop (actual screenshots will come later):
