Note that, portage will want to use the new python targets immediately.
Set for portage, for your next upgrade:
PYTHON_TARGETS="python2_7 python3_4 python3_6"
PYTHON_SINGLE_TARGET="python3_4"
Set for portage, for your next upgrade after that:
PYTHON_TARGETS="python2_7 python3_6"
PYTHON_SINGLE_TARGET="python3_6"
Migrate via,
`emerge --ask --depclean && emerge -1vUD @world && emerge --ask --depclean`
And you should be good to go.
NOTES:
`man emerge`
`/changed-use`
"Unlike --newuse, the --changed-use option does not trigger
reinstallation when flags that the user has not enabled are added or
removed."
`emerge --newuse @world` should fix you up here.
From the news item,
`eselect news read`
`2018-05-22-python3-6`
On *2018-06-22*, Python 3.6 will replace Python 3.5 in the default Python
targets for Gentoo systems. The new default targets will be:
PYTHON_TARGETS="python2_7 python3_6"
PYTHON_SINGLE_TARGET="python3_6"
Hope this helps.
