http://penguinppc.org/bootloaders/yaboot/yaboot-1.3.13.tar.gz instead of... SRC_URI="http://penguinppc.org/projects/yaboot/${P}.tar.gz"
sadly, that's not all -- also they split off the latest release and older releases into different locations Latest release: SRC_URI="http://penguinppc.org/bootloaders/yaboot/${P}.tar.gz" Other releases: SRC_URI="http://penguinppc.org/bootloaders/archived/yaboot/${P}.tar.gz" Thanks for the report Stefan!
