udev homepage isn't reachable anymore. The new homepage is https://git.kernel.org/?p=linux/hotplug/udev.git;a=summary or http://git.kernel.org/?p=linux/hotplug/udev.git;a=summary
HOMEPAGE="http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html" should be HOMEPAGE="http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev/udev.html"
Fixed in 171-r5, 181, and 9999
