[gentoo-user] emerge world needs something, but I don't know what ...

Can anyone help me with this?

    emerge: there are no ebuilds built with USE flags to satisfy
    "dev-python/pygobject:3[python_targets_python3_11(-),cairo]".
    !!! One of the following packages is required to complete your request:
    - dev-python/pygobject-3.50.0::gentoo (Change USE:
    +python_targets_python3_11)
    (dependency required by
    "x11-wm/xpra-4.4.6-r2::gentoo[python_single_target_python3_11]"
    [ebuild])
    (dependency required by "@selected" [set])
    (dependency required by "@world" [argument])


I think this is why my emerge ends, right?

TIA, N952162

This means that pygobject wants PYTHON_TARGETS="python3_11" because
that is what you have set on x11-wm/xpra, and that is because that is
the newest python that xpra-4.4.6-r2 supports. Either upgrade xpra to
the testing version (currently 6.0.1-r1), or add python 3_11 to python
targets for dev-python/pygobject-3.50.0.

I intrepreted your answer (with the help of chatGPT) to mean I should
add this use flag:

    dev-python/pygobject python_targets_python3_11

But I seem to now be in a circular loop  (after similarly updating 21
other projects with that flag):

    emerge: there are no ebuilds built with USE flags to satisfy
    ">=dev-python/setuptools-69.0.3[python_targets_python3_11(-)]".
    !!! One of the following packages is required to complete your request:

    (dependency required by
    "x11-wm/xpra-4.4.6-r2::gentoo[python_single_target_python3_11]"
    [ebuild])
    (dependency required by "@selected" [set])
    (dependency required by "@world" [argument])

If I add that flag, I get:

    emerge: there are no ebuilds built with USE flags to satisfy
    ">=dev-python/jaraco-text-3.7.0-r1[python_targets_pypy3(-)?,python_targets_python3_13t(-)?,python_targets_python3_10(-)?,python_targets_python3_11(-)?,python_targets_python3_12(-)?,python_targets_python3_13(-)?]".!!!

First, python3_11 is an older version, so I would recommend to only
add this flag to specific versions, like so:

=dev-python/pygobject-3.50.0 python_targets_python3_11

And likewise for any others that is really needed. If not you will get
trouble as more and more of these packages drop support for python
3.11. You might need to update the versions here from time to time,
but I think the error messages are easier to understand than when the
support is dropped.

That said, it might be easier to install the newer version of xpra
than adding all these flags, as I had to add much more than your 21 to
get it to want to install this for me. It quickly becomes a mess.
