The current libdnet ebuild (https://github.com/gentoo/gentoo/blob/master/dev-libs/libdnet/libdnet-1.12.ebuild) references https://libdnet.googlecode.com/files/${P}.tgz and https://fragroute-ipv6.googlecode.com/files/${P}.ipv6-1.patch.gz which both return 404 errors. The IPv6 patch is now at https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/fragroute-ipv6/libdnet-1.12.ipv6-1.patch.gz Libdnet has moved to https://github.com/dugsong/libdnet (see https://code.google.com/archive/p/libdnet/) I'm going to omit the superfluous emerge --info details, as the environment is unimportant. This shouldn't be an issue if you can access the gentoo distfiles mirrors. This will only be a problem if the distfiles server of your choice is down, so I put it as a minor bug.
