As udev-084.tar.bz2 isn't yet available on distfiles.gentoo.org, I downloaded it from http://www.kernel.org/pub/linux/utils/kernel/hotplug/?C=N;O=D - http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev-084.tar.bz2 and put it in my distfiles directory. I then tried to emerge udev-084 and get: !!! Digest verification Failed: !!! /0b/Gentoo/portage/distfiles/udev-084.tar.bz2 !!! Reason: Failed on RMD160 verification !!! Got: b009ac94a8e4599d746d0c4f9de9e1ea3898b1a3 !!! Expected: d93b802a3b2f925ec9ac73045917d335c3044621 Seems to me that the shipped digest is wrong.
Nevermind. My download got corrupted somehow.
