OK - so now I'm not so sure what the correct next step is. The
xorg-server emerge completed cleanly but the contents of the
extensions directory are a single file, not a link and now eselect
opengl set 1 fails:

The second one is a link that I suppose it broken because it's showing
up in red. However I don't know if it was there after removing
everything and redoing the emerges as I didn't check for it.

Basically, if the 'thing' in extensions is supposed to be a link, then
where is the real libglx.so supposed to go?

Con-fuzed...
