I just restarted CorePure64 with nothing set onboot:
tce-load -i Xorg-7.7 flwm aterm wbar
startx
works, libGL is not loaded and not needed
..and tce-load -i Xorg-7.7-3d flwm aterm wbar
startx
works and libGL is loaded
What are you loading to start an x11 gui?
Did you update the following:
libva22.tcz.dep
xorg-server.tcz.dep
