The ebuild selected to satisfy "asciidoc" has unmet requirements. - app-text/asciidoc-8.6.10::gentoo USE="-examples -graphviz -highlight -test" ABI_X86="(64)" PYTHON_SINGLE_TARGET="(-pypy) -python2_7" PYTHON_TARGETS="python2_7 (-pypy)" The following REQUIRED_USE flag constraints are unsatisfied: exactly-one-of ( python_single_target_pypy python_single_target_python2_7 ) The above constraints are a subset of the following complete expression: exactly-one-of ( python_single_target_pypy python_single_target_python2_7 ) python_single_target_pypy?

If you set PYTHON_SINGLE_TARGET="python3_6" globally then you wipe out the profile-supplied python2_7 setting for asciidoc [1], and you need to re-apply it via your own package.use [1] https://gitweb.gentoo.org/repo/gentoo.git/tree/profiles/base/package.use#n8
