einfo "Fetching Gentoo Developer seed file..."
gkeys fetch-seed -C gentoo-devs || die "Unable to fetch seeds"
Bad puppy. No random network fetching!
(Makes it uninstallable in situations where for example no external network access is given and distfiles are available over NFS ...)
gentoo-developer seed files really aren't necessary for normal users, so this should, at least, be a use flag anyways.
Or use pkg_config, or print an einfo - the point is, fetching random crap will fail, and cause angry bug reports, so please have all fetchable items in SRC_URI
