Can someone please fix this? I've been hoping someone other than myself would report this for the last several days.
The issue is because you have a newer version installed so Portage already has those solutions. The problem crops up because Portage does not yet support backtracking and as such can't downgrade it's previous decision. If you downgrade the version by hand, it will resolve this for you. The fix will be out in the next Portage version (2.2 or 2.1.4) should contain the fix.
Yes, I believe it is a portage problem; or possibly one could alternatively blame the ebuild. I've unmerged mjpegtools altogether, and I'm still getting the problem when trying 'emerge -pDuv world'. Your explanation for closing the bug leaves a bit to be desired. I downgraded mjpegtools manually, and: # emerge -pDuv world These are the packages that would be merged, in order: Calculating world dependencies - !!!

Yes. A mask will solve the problem. As I stated in my instructions, the proper fix would have been to hand emerge (emerge --oneshot =media-video/mjpegtools-1.8*) the proper version and it would go away. Now that you've unmerged the current version. The only fix is to add a mask to /etc/portage/package.mask. This isssue is bug #1343.
Yes, the mask solved the problem. Thanks. I actually tried that first, but it didn't work then (still needed to manually downgrade I guess), so had backed it out. And then did the manual downgrade and forgot to try the mask again. Anyways, everything looks good now. Thanks again.
(In reply to comment #3) > Yes. A mask will solve the problem. And if a mask is necessary it should be part of the official distribution. Every time I 'emerge --sync && emerge --update portage', my hand-entered masks disappear. It's getting tedious. > As I stated in my instructions, the proper > fix would have been to hand emerge (emerge --oneshot > =media-video/mjpegtools-1.8*) the proper version and it would go away.

Depgraph creation failed. Note that nothing in this part of the deptree is being remerged - it's all up to date with appropriate matching versions (according to your previous comments), but portage can't tell. It's a portage bug, or a bug in one of the ebuilds listed. Please reopen this bug - _somebody_ can fix it.
