On Gentoo the eix program is MUCH faster than emerge for listing package names. I've left the emerge code in as a 2nd choice because not every Gentoo system has eix installed (although they should). Also, the emerge code didn't seem to produce any output on my system. Signed-off-by: Grissiom <chaos.proton@gmail.com>
