This was exactly what I was looking for. Since the following command did not 
produce any relevant output I can confirm that this works for everything 
currently in portage.

# cd /usr/portage && \
	find . -name '*.ebuild' | sed -e 's/\.ebuild$//' | \
	awk -F/ '{print $2"/"$4}' | sed -r 's/-[^-]+(-r[0-9]+)*$//' | \
	awk -F/ '{system("eix -C "$1" -e "$2" -c | grep -q ^Found\\ 1\\ matches || \
	 echo "$0)}'

Thank you to everyone who replied. :)
