Code:
cloc3Lnv ~ # grep -rH zope /etc/portage/package.use/
/etc/portage/package.use/pythonTargets:dev-python/zope-interface PYTHON_TARGETS: python2_7 python3_4 python3_5 python3_6
/etc/portage/package.use/pythonTargets:dev-python/namespace-zope PYTHON_TARGETS: python2_7 python3_4 python3_5 python3_6
/etc/portage/package.use/pythonTargets:dev-python/zope-event PYTHON_TARGETS: python2_7 python3_4 python3_5 python3_6
Code:
cloc3Lnv ~ # eselect python list
Available Python interpreters, in order of preference:
  [1]   python3.6
  [2]   python3.5
  [3]   python3.4
  [4]   python2.7 (fallback)
  [5]   jython2.7 (fallback)
Code:
cloc3Lnv ~ # emerge -pv dev-python/zope-interface

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds to satisfy "dev-python/namespace-zope[python_targets_pypy(-)?,python_targets_pypy3(-)?,python_targets_python2_7(-)?,python_targets_python3_4(-)?,python_targets_python3_5(-)?,python_targets_python3_6(-)?,-python_single_target_pypy(-),-python_single_target_pypy3(-),-python_single_target_python2_7(-),-python_single_target_python3_4(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-)]".
(dependency required by "dev-python/zope-interface-4.4.2::gentoo" [ebuild])
(dependency required by "dev-python/zope-interface" [argument])


le ho già provate un po' tutte, ma non ne esco.
almeno capissi che cosa significa quel messaggio di errore (there are no ebuilds ...).

in make.conf?
Code:

cloc3Lnv ~ # grep PYTHON_TARGETS /etc/portage/make.conf
PYTHON_TARGETS="python2_7 python3_5 python3_6"

Ok allora devi smascherare le use flag, perche' in un sistema stable sono mascherare.

/usr/portage/profiles/base/use.stable.mask:
# Michał Górny <mgorny@gentoo.org> (25 Jan 2017)
# Early pre-stabilization mask for dev-lang/python:3.6
python_targets_python3_6
python_single_target_python3_6

...

# Mike Gilbert <floppym@gentoo.org> (02 Oct 2015)
# Needs dev-lang/python:3.5 stable
python_targets_python3_5
python_single_target_python3_5

...


Quindi devi metterele in /etc/portage/profile/use.mask
Code:
echo "-python_targets_python3_5" >> /etc/portage/profile/use.mask
echo "-python_targets_python3_6" >> /etc/portage/profile/use.mask

sembra sufficiente commentare le quattro righe che hai indicato tu.
avevo letto di questa procedura, ma ne fraintendevo completamente il significato.

perché bisogna toccare anche /etc/portage/profile/use.mask?

Perche' al prossimo sync il file /usr/portage/profiles/base/use.stable.mask viene sovrescritto mentre quello in /etc/portage/profile/use.mask no

e siccome use.mask serve a mascherare e io voglio smascherare, uso il segno meno, che maschera la mancanza della flag.
:) contorto, ma pervenuto.
grazie.
