Just to add, since I run a mix of unstable and stable, sometimes I find
that a package that is running unstable now needs another package that
is also unstable, either a new dependency or just out of sink somehow.
Sometimes I find that by adding the -t option. I then have to add that
new required package to the keyword file.
I might add, what works one time to find the problem may not work every
time. You need to try different methods until you find the problem. It
never hurts to hope the first method you try works tho. LOL ;-)

Well, I have gotten it down to this one bug which is missing IUSE, so how to
add it ?
Calculating dependencies . ... .... done!
Dependency resolution took 14.32 s (backtrack: 0/200).
emerge: there are no ebuilds built with USE flags to satisfy
"dev-libs/liblouis[python,python_targets_python3_13(-)]".
!!! One of the following packages is required to complete your request:
- dev-libs/liblouis-3.30.0::gentoo (Missing IUSE: python)
- dev-libs/liblouis-3.29.0::gentoo (Missing IUSE: python)
(dependency required by
"app-accessibility/orca-9999::local_ebuilds[braille,python_single_target_python3_13]"
[ebuild])
(dependency required by "gnome-base/gdm-47.0::gentoo[accessibility]"
[installed])
(dependency required by "gnome-base/gnome-shell-47.8::gentoo" [ebuild])
(dependency required by "x11-terms/gnome-terminal-3.56.2::gentoo[gnome-shell]"
[ebuild])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])
:-) :-)
