Here is a script to do it:
cat /var/lib/portage/world | \
while read line; do
count=`equery depends "$line" | wc -l`
test $count -gt 0 && echo $line
done
This will output every package listed in world that is a dependancy of
something else. Of course, you need a recent version of gentoolkit to
get equery.
