A world update failed this morning because of a blocking reference to both sys-devel/llvm-3.9.1-r1 and sys-devel/llvm-4.0.0. It turned out that the former was required by media-libs/mesa-17.0.1, which was installed with VIDEO_CARDS=amdgpu (amongst others). Removing this and first re-emerging mesa, then performing a world update, solved the problem. I was able to re-enable VIDEO_CARDS=amdgpu afterwards.
Those blockers were too much for portage to handle here as well when upgrading world, but it did not have a problem handling them when doing an `emerge -1atv llvm clang mesa kdevelop`. kdevelop was in there because it was originaly emerged using the cxx USE flag that caused it to depend explicitely on slot 0.
Could you please add the full portage output showing the blockers?

I wonder if this is bug #612772.
yes *** This bug has been marked as a duplicate of bug 612772 ***
at least one of them is. I didn't bother reading them all.
