I have /etc/portage/make.conf set to use Python 2.7 and 3.6 USE_PYTHON="2.7 3.6" PYTHON_TARGETS="python2_7 python3_6" Recent update to sys-apps/util-linux-2.29.2-r1 raises the following error about a missing python single version: !!!

This isn't a bug, if you take python3_4 out of PYTHON_TARGETS, you need to adjust PYTHON_SINGLE_TARGET as well. And FYI a lot of packages aren't going to allow python3_6 yet.
