[gentoo-user] Going through these one by one.

[Steven Lembark]

Based on:

    2020-04-22  Python 3.7 to become the default target

I'd have thought that using:

    PYTHON_TARGETS="python2_7 python3_7"
    PYTHON_SINGLE_TARGET="python3_7"

and 

    emerge --depclean;
    emerge -1vUD @world;
    emerge --depclean;

should have updated my system. I'd done a fairly recent 
"emerge @world" and it completed so I'd have thought that
everything was up to date.

The depclean step gave me:

 * Have you forgotten to do a complete update prior to depclean? The
 * most comprehensive command for this purpose is as follows:
 *
 *   emerge --update --newuse --deep --with-bdeps=y @world


At this point pretty much anything I update runs into:

    !!! All ebuilds that could satisfy "sys-apps/portage[python_targets_python2_7(-),python_targets_python3_6(-),-python_single_target_python2_7(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-)]" have been masked.
    !!! One of the following masked packages is required to complete your request:
    - sys-apps/portage-9999::gentoo (masked by: missing keyword)
