Please attach debug output: emerge -DuNa @world --debug &> debug.log
Created attachment 280323 [details] emerge -DuNp @world --debug Here it is. (BTW, the bug has been mark as CONFIRMED as I have EditBugs privileges, and I didn't find the input form to change it during initial bug submission)
Here's the most interesting part of the log: backtracking due to slot conflict: first package: (x11-libs/libdrm-2.4.22::gentoo, installed) second package: (x11-libs/libdrm-2.4.26::gentoo, ebuild scheduled for merge) package to mask: (x11-libs/libdrm-2.4.22::gentoo, installed) slot: x11-libs/libdrm:0 parents: ((media-libs/mesa-7.9::fulax, installed), '<x11-libs/libdrm-2.4.23'), ((x11-drivers/xf86-video-nouveau-0.0.16_pre20110711::gentoo, ebuild scheduled for merge), '>=x11-libs/libdrm-2.4.24[video_cards_nouveau]') You can see that backtracking creates a temporary mask for the installed libdrm-2.4.22 instance, in order to try and solve the conflict. Maybe we can handle this by making it mask all other instances of libdrm-2.4.22 at the same time, given that none of them will satisfy the >=x11-libs/libdrm-2.4.24[video_cards_nouveau] atom that triggered the conflict.

Maybe this comes with the --autounmask feature. Since a few weeks, --autounmask suggests me to override my package.mask by adding entries in portage.unmask. If I disable this feature, I get: $ emerge -DuNp --autounmask=n @world These are the packages that would be merged, in order: Calculating dependencies... done! Total: 0 packages, Size of downloads: 0 kB !!! The following update has been skipped due to unsatisfied dependencies: x11-drivers/xf86-video-nouveau:0 !!! All ebuilds that could satisfy ">=x11-libs/libdrm-2.4.24[video_cards_nouveau]" have been masked. !!! One of the following masked packages is required to complete your request: - x11-libs/libdrm-2.4.26::gentoo (masked by: package.mask) - x11-libs/libdrm-2.4.25::gentoo (masked by: package.mask) - x11-libs/libdrm-2.4.24::gentoo (masked by: package.mask) (dependency required by "x11-drivers/xf86-video-nouveau-0.0.16_pre20110711" [ebuild]) For more information, see the MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook.

This would result in an unsatisfied dependency, instead of a skipped update. The problem is that the mask for the installed libdrm is created for the update of nouveau. Some backtracks later it figures out that the update of nouveau leads to an unsolvable conflict and masks the update. At this point the masks created for libdrm because of the update for nouveau should be removed.
