James Bowlin 46986ad4c2 Use eix instead of emerge when possible
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.
