I ran "equo install eix" a couple of minutes ago, it installed correctly... But when I ran update-eix afterward, it came up with a lot of errors (EDIT: I can't recreate the problem.. Maybe if you already ran update-eix before, it works?)
I thought maybe its a problem with eix itself, but when I emerged it, it worked..
Maybe its a problem with the sabayon repository?
EDIT: I noticed that the version of Eix on equo is 0.13.2 and on portage its 0.13.3.. Maybe it is a problem with eix after all
