out of curiousity, does re-emerging giflib do anything?
you must have emerge'ed libungif at some point. Re-emerge giflib and all is good. If you still want libungif, re-compile with gif USE flag.
Argh, I hate the giflib/libungif und USE=gif difficulty, particularly because qt-3.3.3 installes both version.
