The current ebuilds of portage in the funtoo tree are 2.4.1-r1 and 2.4.3-r1. There are no such versions in the Gentoo tree, creating confusion. The ebuilds themselves reference exact releases of portage, 2.2.26 and 2.3.2, respectively. But many mirrors appear not to have these versions (https://dev.gentoo.org/~dolsen/releases has them, but what if they get removed here, too?). Why does Funtoo need to be different and weird with respect to Gentoo?
