He añadido PYTHON_TARGETS="python2_7 python3_5 python3_4"a mi /etc/portage/make.conf.
Al intentar instalar cualquier programa que admita destinos de Python, sucede lo siguiente:
sudo emerge --ask dev-python/google-api-python-client
These are the packages that would be merged, in order:
Calculating dependencies... done!

Would you like to merge these packages? [Yes/No]
Como puede ver, python3_5 está deshabilitado por algún motivo y no sé cómo solucionarlo. También intenté agregar python_targets_python3_5a mis indicadores USE, pero no tuvo ningún resultado.
$ eselect python list
Available Python interpreters:
[1] python2.7
[2] python3.4
[3] python3.5 *
¿Qué debo hacer para habilitar la compatibilidad con la bandera python3.5?
Respuesta1
Finalmente encontré cómo resolver este problema.
Debe editar /usr/portage/profiles/base/use.stable.masky comentar las siguientes líneas:
python_targets_python3_5
python_single_target_python3_5
Y aquí vamos:
sudo emerge --ask dev-python/google-api-python-client
These are the packages that would be merged, in order:

ACTUALIZAR: Estos cambios serán sobrescritos por las actualizaciones del sistema, por lo que deberá actualizar /etc/portage/profile/use.stable.maskcon las siguientes líneas:
-python_targets_python3_5
-python_single_target_python3_5
