I am still on the 2013 profile, and I therefore have
PYTHON_TARGETS=python2_7 python3_5.
The other day I had to install python 3.6 for reasons unrelated to
portage or other packages. I thought I would reduce my overall snake
footprint by removing 3.5 _if_ it wasn't really necessary anymore. To
that end, I removed the line
dev-lang/python:3.5
from /etc/portage/world, and then I did emerge --depclean. I was
somewhat surprised when portage charged ahead and removed python 3.5,
but I said ok maybe it automatically changed the TARGETS of the
dependencies and they will be rebuilt next time. But _no_, checks with
equery and emerge -p show that all python code providing packages still
have python_targets_python3_5 on, and python_targets_python3_6 off.
This is disappointing. It looks like I have to do 2 things manually:
* set PYTHON_TARGETS="python2_7 python3_6" - where? In make.conf? Will
it override the profile setting?
* make sure dev-lang/python:3.6 stays in the world file, even if it is
not needed by me directly
Or I am badly confused as I often am ;-)
