emerge --info output

After the upgrade to python3.6:

$ sudo emerge -aqv asciidoc


!!! Problem resolving dependencies for app-text/asciidoc

!!! 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? ( python_targets_pypy ) python_single_target_python2_7? ( python_targets_python2_7 )
Comment 1 Ben Kohler gentoo-dev 2018-06-28 21:52:01 UTC
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
