Hace poco tuve un problema intentando eliminar un paquete de los llamados slotted en Gentoo, a continuación muestro cómo lo resolví.
Primero debemos usar equery list <pkg> para listar los paquetes que coinciden con el nombre del paquete a eliminar:
$ equery list emacs
* Searching for emacs ...
[IP-] [ ] app-editors/emacs-24.5-r3:24
[IP-] [ ] app-editors/emacs-25.1:25
Hay dos paquetes de emacs instalados, cada uno en un slot distinto, :24 y :25. Para borrar el más antiguo, ejecutamos:
$ sudo emerge -C emacs-24.5-r3:24
Password:
* This action can remove important packages! In order to be safer, use
* `emerge -pv --depclean <atom>` to check for reverse dependencies before
* removing packages.
app-editors/emacs
selected: 24.5-r3
protected: none
omitted: 25.1
All selected packages: =app-editors/emacs-24.5-r3
>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.

* Regenerating site-gentoo.el for GNU Emacs (postrm) ...
[ ok ]
* ... 4 site initialisation files included.
* Regenerating GNU info directory index...
* Processed 140 info files.
Tras eliminar el paquete, comprobamos qué otros paquetes dependían de él
$ equery depends emacs-24.5-r3:24
* These packages depend on emacs-24.5-r3:24:
app-emacs/emacs-common-gentoo-1.5 (virtual/emacs)
app-emacs/markdown-mode-2.1 (>=virtual/emacs-23)
