Actually, you have multiple reasons for the aborted merge. Either the blockers or the slot conflicts would be enough to make it abort. It seems to me that emerge is behaving as designed, given the conflicts that you have. Can you suggest some way to improve it? Note that the libreoffice blockers are fixed if you sync (see bug #390271). The slot conflicts might resolve automatically if you use a higher emerge backtrack setting, such as `--backtrack=30`.

Either the blockers > or the slot conflicts would be enough to make it abort. The slot conflicts alone (I p.masked >=libreoffice-l10n-3.4.4, which caused the block) do not cause an abort. They both will be resolved automatically by skipping the update. So the reason for the aborted merge seems to be the blockers, only. However, portage suggests that the reason would be the slot conflicts, which appears to be wrong. My suggestion: Print the blockers as the actual reason for the abort, not the slot conflicts. It's related to this change, from bug #385391: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=77b651300731ec007cd535a83b8ee9a898602783 (In reply to comment #3) > My suggestion: Print the blockers as the actual reason for the abort, not the > slot conflicts. The thing is, it doesn't know that the blockers are the only reason, because the blockers make it quit before it tries to find a solution for the slot conflicts.

Could you apply the "slot conflict display" to blockers, too? And just display both? And possibly add the (short!) hint that slot conflicts can in some cases be resolved automatically by skipping upgrades ("... see manpage for more info")? Or just resolve everything, if possible, before bailing out. Or does that take too long (runtime speed)? I think we can consider this fixed since 2.2.0_alpha180, by the following commit: https://github.com/gentoo/portage/commit/f4058826bd2928fb9f12b5cac1d225d79e58c993 |
emerge -uDN @world -pv aborts with following message: --- [...] [blocks B ] app-office/libreoffice-bin ("app-office/libreoffice-bin" is blocking app-office/libreoffice-3.4.4.2-r1) [blocks B ] app-office/libreoffice ("app-office/libreoffice" is blocking app-office/libreoffice-bin-3.4.3.2-r1) Total: 33 packages (25 upgrades, 5 new, 1 in new slot, 2 reinstalls), Size of downloads: 320,165 kB Conflict: 2 blocks (2 unsatisfied) !!!

Instead the new version of libreoffice-l10n pulls in a newer version of libreoffice{,-bin}, and since there is no libreoffice-bin of that version, it pulls in libreoffice instead, which then blocks libreoffice-bin. Hence I consider the displayed message misleading. Package masking ">=app-office/libreoffice-l10n-3.4.4-r1" allows me to merge with following message: --- [...] WARNING: One or more updates have been skipped due to a dependency conflict: sys-apps/gawk:0 (sys-apps/gawk-4.0.0::gentoo, ebuild scheduled for merge) conflicts with <sys-apps/gawk-4.0.0 required by (dev-db/virtuoso-server-6.1.3-r1::gentoo, installed) sys-devel/llvm:0 (sys-devel/llvm-2.9-r2::gentoo, ebuild scheduled for merge) conflicts with =sys-devel/llvm-2.8* required by (www-plugins/lightspark-0.5.2.1::gentoo, installed) !!!
