Well, there is probably a better way to write this script, but here is
a method that will do it with bash.  The idea is for each package in
portage, to determine whether that is installed or not.  This seems a
bit easier than working backwards from the installed package database:

cd /usr/portage
find . -name "*.ebuild" | sed -e 's/\.\///g' | while read ebuild; do
    pkg=`dirname $ebuild`
    category=`dirname $pkg`
    pkgdir=`basename $ebuild .ebuild`
    test -d /var/db/pkg/$category/$pkgdir && echo $pkg
done | sort

This works, but it does seem to take a long time!
