This is a gentoo overlay including programs of the Pyneo project.
Using this overlay is easy. Make sure you have layman installed, using the git USE-flag, and set up, e.g. as described here.
After that you just have to add this overlay using:
layman -o "http://raw.github.com/tg--/gentoo-pyneo/master/overlay.xml" -f -a pyneo
That's it!
