portage-2.2_rc51 and portage-2.2_rc52 is broken when dealing with blockers. On my ~amd64 system, with portage-2.2_rc50, when installing deluge, I get the following blockers report: # emerge -vtp deluge These are the packages that would be merged, in reverse order: Calculating dependencies... done!

The KeyError is handled in 2.2_rc53, but I'm still not sure why it happened.
Created attachment 211408 [details, diff] fix the KeyError Save this patch as /tmp/blocker_keyerror.patch and apply as follows: patch /usr/lib/portage/pym/_emerge/depgraph.py /tmp/blocker_keyerror.patch
This is fixed in 2.1.7.9 and 2.2_rc54.
