Humm...removing xorg-server allowed me to set OpenGL to xorg-x11
without an error:


myth12 ~ # emerge -C xorg-server

 x11-base/xorg-server
    selected: 1.5.3-r6
   protected: none
     omitted: none

>>> 'Selected' packages are slated for removal.

 * GNU info directory index is up-to-date.
myth12 ~ # updatedb
myth12 ~ # ls -al /usr/lib/opengl/xorg-x11/extensions/
ls: cannot access /usr/lib/opengl/xorg-x11/extensions/: No such file
or directory
myth12 ~ # eselect opengl list
Available OpenGL implementations:
  [1]   xorg-x11
myth12 ~ # eselect opengl set 1
Switching to xorg-x11 OpenGL interface... done
myth12 ~ #

and now mesa seems to be building.

Problem solved - sort of. ;-)
