# NOTE: ignore app-games/fortune-mod as a dep. it is pluggable and won't
#       really matter if it isn't there. Maybe we should have a 'games'
#       USE flag...

# smithj says (2005-07-26):
# MOTIF WAS REMOVED FOR A REASON! The motif version has not been maintained for
# some time, and has problems both at build-time and run-time. This ebuild
# (4.22-r3) is going to force gtk support and disable motif support. Hopefully
# the users won't complain too much...
