I am not sure if it would be possible to handle this case as I remember to have hitted it sometimes recently Thanks a lot
Also, it looks like even with eselect 1.4.5 keyworded, I need to explicitly run "emerge -1v cairo eselect" as, otherwise, emerge keeps failing without even trying to update eselect
