Package: libgle3 Package: xscreensaver-gl These packages depend on xlibmesa-glu | libglu1 but should also allow | libglu1c2 This since the new xorg packages only fulfil libglu1c2 (alternately, libglu1-xorg could provide libglu1.... i don't know enough to speak to which is right)
What I can say is that libgle3 and xscreensaver-gl appear to work fine when I add the | libglu1c2 by hand in the apt lists -Darren Creutz
