Created attachment 458948 [details] mdadm-3.4-r1.ebuild mdadm-3.4 can't download a Debian dependency because it's been removed from their mirrors. Fortunately, all that's needed is a pointer to the latest mdadm tarball from the Debian mirrors. New ebuild is attached.

I ran into this issue on a brand new stable installation. The given fix works well.
update your GENTOO_MIRRORS settings to include up-to-date Gentoo mirrors. changing the 3.4 tarball to use a diff deb patchset means bumping it. and at this point, we already have newer versions available in the tree which will go stable.
