The slot conflict(s) shown above involve package(s) which may need to !!! be rebuilt in order to solve the conflict(s). However, the following !!! package(s) cannot be rebuilt for the reason(s) shown: (media-sound/mpd-0.21.10:0/0::media-kit, installed): ebuild is masked or unavailable (media-sound/ncmpcpp-0.8.2-r1:0/0::media-kit, installed): ebuild is masked or unavailable 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. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically.
