A cron job here runs "emerge --sync && emerge --update --fetchonly"
every day at 0300.

This system has been fried ever since

      Title                     Python 3.7 to become the default target

    On 2020-05-06 (or later), Python 3.7 will replace Python 3.6 as one
    of the default Python targets for Gentoo systems.  The new default
    values will be:

Followed those instructions -- don't use python for anything here
and the local copies of what I actually use are in /opt/perl, 
/opt/postgresql, etc, built from git checkouts.

At this point I've added and removed python single and multiple
target entries from make.conf & package.use/local, with various
sets of values and exclusions. 

A bare sync tells me there is a new version of portage available,
installing it fails, however with:

    # emerge --sync;

    <snip>

    Action: sync for repo: gentoo, returned code = 0

     * An update to portage is available. It is _highly_ recommended
     * that you update portage now, before any other packages are updated.

    * To update portage, run 'emerge --oneshot sys-apps/portage' now.


    # emerge --oneshot sys-apps/portage 2>&1 | tee a;

Q: Is there any way to clean up python at this point without 
   a full re-install?
