Most details on gentoo package versions are explained here:

It doesn't say if trailing .0 version components are significant but
from a quick experiment with dummy packages foo-0.1 and foo-0.1.0 Gentoo
does consider 0.1.0 > 0.1. That is, it considers version 0.1.0 to be an
upgrade on 0.1 where as 0.1 is a re-install.
