No buildpkg on this system.  :-(

I'm not sure how to
fix that.  Basically, portage stores data on what is installed in /var
but the packages are in /, mostly /(s)bin and /usr.  Basically, portage
thinks one thing but the truth is something else.  I suspect emerge
isn't happy since it is so confused.

Emerge is not happy when it tries to use package versions which the
filesystem does not have installed yet.  I'll try once more to tweak
python targets in case I can get emerge to build a working toolchain. 
If
that doesn't work I'll fetch a stage 3, build what I need as binaries
and
then emerge them on the live system before I carry on.

With the public binhost you should be able to skip the stage3 and go
straight to emerging a binary toolchain. I'd suggest you should even use
--getbinpkg --emptytree @world for consistency.

Thank you Eli, I'll take a look at this approach as it will be a quicker
option.

I thought before I use binaries I better see how big the job ahead might be.  
I've set:

*/* PYTHON_TARGETS: -* python3_12 python3_13
*/* PYTHON_SINGLE_TARGET: -* python3_13

then tried to emerge python:

emerge -1aDv -e dev-lang/python

It wouldn't start because it complained packages (any/all) were masked by 
keyword.  This is a stable OS, so I do not understand why it thinks stable 
versions are masked:

$ emerge --info | grep ACCEPT_KEYWORDS
ACCEPT_KEYWORDS="amd64"

Anyway, I tried it this way, which allowed all but 1 out 481 packages to 
emerge successfully:

ACCEPT_KEYWORDS="amd64" emerge -1aDv -e dev-lang/python

Then this happens:

OK, I thought I better install what it seems to be complaining about, because 
it was not installed in this system:

ACCEPT_KEYWORDS="amd64" emerge -1av dev-python/pyatspi

However, it still complains:

# python -c 'import atspi'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
    import atspi
ModuleNotFoundError: No module named 'atspi'

Apparently, it is a media-libs/assimp QT bug:

https://bugreports.qt.io/browse/QTBUG-84037

I've re-emerged media-libs/assimp, but the bug remains ... I wonder how it had 
been installed originally.  Is there anything I can do about this?


Grasping at straws here.  Could it be that it was built against one version of python but another is now installed and active, and not the one it is built against? 

I looked at the USE flags on my system.  The only ones are for python targets and test, which us lowly users don't use.  The only problem that I can think of is a problem with python version. 

Another thought.  I have made the switch to python 3.13 but have other versions installed for a few packages that need them.  This is what I show for what python is selected. 



root@Gentoo-1 / # eselect python list
Available Python interpreters, in order of preference:
  [1]   python3.13
  [2]   python3.12 (fallback)
  [3]   python3.11 (fallback)
root@Gentoo-1 / #


If you still on 3.12, it may show it as selected, not fallback.  Anyway, checking that and seeing what the system is working with might give a clue.  Maybe.  It's another straw at least.
