Thanks for the help, but I still have the problem.
emerge --info showed the same for PYTHON_SINGLE_TARGET="python3_5" and
PYTHON_TARGETS="python2_7 python3_5"
eix -I python shows 2.7.14 and 3.4.5 on both systems
grep -i python /etc/portage/make.conf
has no hits on either system
eselect python list showed the same two version (3.4 and 2.7)
but in *opposite* order. I issued
eselect python set 2
on the failing 7450 and now both report
Available Python interpreters, in order of preference:
[1] python3.4
[2] python2.7
I don't believe I need to "activate" this change, right?
However, after making the above change the 7450 still fails to emerge
update world saying
Calculating dependencies -
!!! Problem resolving dependencies for sys-process/systemd-cron from @selected
... done!
!!! The ebuild selected to satisfy "sys-process/systemd-cron" has unmet
requirements.
