emerge layman (if you don't have it yet)

Edit /etc/layman/layman.cfg and add this: (second line)

overlays  : http://www.gentoo.org/proj/en/overlays/layman-global.txt
            https://raw.github.com/ndt/ogo-ndt/master/overlay.xml
            
Then:
  layman -L
  layman -a electro-nic

then you can emerge anything from the electro-nic overlay
