Before I spend a lot of time backtracking all of this...

Q: Are either of these issues well-known pathologies of emerge?

Recently built a new Gentoo system by creating a new LV, extracting stage3-amd64-openrc-20211205T170532Z.tar.xz and going through the
handbook stages to get a running sytem.

I then installed a variety of packages I have on the current system
like fonts, claws-mail.

Catch is that I cannot update the sytem:

# $emerge --update --fetchonly @world;
Calculating dependencies... done!

The following packages are causing rebuilds:

(x11-base/xorg-server-1.20.14:0/1.20.14::gentoo, ebuild scheduled for merge) causes rebuilds for:
(x11-drivers/xf86-input-synaptics-1.9.1:0/0::gentoo, ebuild scheduled for merge)
(x11-drivers/xf86-input-evdev-2.10.6:0/0::gentoo, ebuild scheduled for merge)

emerge: there are no ebuilds to satisfy ">=dev-lang/python-exec-2:2/2=[python_targets_python2_7(-),python_targets_python3_6(-),-python_single_target_pypy(-),-python_single_target_pypy3(-),-python_single_target_python2_7(-),-python_single_target_python3_5(

(dependency required by "@world" [argument])


It seems that I have a recent enough python-exec installed: 2.4 >= 2.2.

But I also seem to have a recent markupsafe, if 2.0.1 >= 0.9.2??

I may well be wront, but it looks like the problems are not due to
version, but to python-target mismatches.  You may need to rebuild some
stuff first, such as pytest-runner and mako.

Python target troubles are indeed common around major python version
upgrades, which we've had quite a few of lately.

In your case, I would try running a depclean, dev-python/pytest-runner
does not seem to be in the tree at all, so complaining about not
finding a newer version satisfying the wanted python targets makes
sense there. Removing outdated packages is almost always helpful in
these instances.

Arve

You are probably right: I've spent more time playing with
PYTHON*TARGET variables and succesive rebuilds on this machine
than actually doing any work for about a year. Annoyance is
that I don't do anything else with Python here so it's only
for the package manager.

This is for a fresh build from a recent stage3. It shouldn't
be this painful to just start a new system.

Sorry for the delay.

With a new system, I would think you should not need to alter the
profile defaults in any way. Once you do anything manually to those
python variables, it likely devolves into a black hole.

I would find any python-target related variables in any portage config
files, and seriously consider removing them.

As someone recently suggested in a different thread, start with just
"emerge @system" then "emerge @world" (without any non-default options)
and only when that is done, start adding back the --newuse and --deep options.

The other replies have also been good - in terms of where to start
looking. Also - which versions of python do you have installed, and
which do you actually need?
