Udev 171 splits out the extras use flag into separate use flags. As a result, the ebuilds for this package need the following changes: sys-fs/udev[extras] needs to become: || ( >=sys-fs/udev-171[useflag] >= sys-fs/udev145[extras] ) "useflag" in this example should be replaced with whatever the use flag is for udev-171 that your package needs. This should not require a revbump since we are just modifying use flags.
Seems to be flag gudev, only. I dared touching this myself: + 09 Jun 2011; Sebastian Pipping <sping@gentoo.org> cheese-2.32.0.ebuild: + Add >=sys-fs/udev-171[gudev] as an alternative dependency to + >=sys-fs/udev-145-r1[extras] (bug #370381) + Closing, please re-open as needed.
