It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.


The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by app-accessibility/orca-42.3::dantrell-gnome-42
# required by kde-plasma/plasma-meta-5.25.5::gentoo[accessibility]
# required by @selected
# required by @world (argument)
>=app-accessibility/at-spi2-atk-2.38.0 -abi_x86_32
