Typing "eselect bashcomp help" gives me [...] Extra actions: /usr/share/eselect//libs/core.bash: line 115: /usr/bin/sed: No such file or directory Changing the given line to use /bin/sed helps.
How did your sed end up there?
Ooops, apparently it got lost somehow (makes me frightened). It was still there two weeks ago (checked a backup). Actually /usr/bin/sed is a symlink to /bin/sed. So please forget you ever saw this :-/
There has to be done some research to this problem nevertheless. My sed just ended up without a symlink in /usr/bin and only available in /bin. I therefore had the same error as mentioned in the original report when 'eselect opengl set ati'. I don't know when or where this happened, but I know I didn't delete the symlink myself, so it must have happened last time I updated sys-apps. Should I file over there?
Got the same just now
