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 ebuild selected to satisfy ">=media-libs/libmediaart-1.9.1:2.0[introspection]" has unmet requirements.
- media-libs/libmediaart-1.9.4::gentoo USE="gtk introspection qt5 -test -vala" ABI_X86="(64)" 

  The following REQUIRED_USE flag constraints are unsatisfied:
    at-most-one-of ( gtk qt5 )

  The above constraints are a subset of the following complete expression:
    at-most-one-of ( gtk qt5 ) vala? ( introspection )

(dependency required by "media-sound/gnome-music-3.32.2-r1::gentoo" [installed])
(dependency required by "gnome-base/gnome-extra-apps-3.32.2::gentoo[tracker]" [installed])
(dependency required by "gnome-base/gnome-3.32.2::gentoo[extras]" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])

Das Problem wurde durch Hinzufügen von libart in die package.mask gelöst
