Не получается обновить portage-2.3.5

Сделал eix-sync и при попытке обновить portage получаю ошибку. Переустановка python-а не помогает.
Откатывать /usr/portage до более старой версии?

# emerge -av1 portage

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

Calculating dependencies... done!

!!! All ebuilds that could satisfy ">=dev-lang/python-exec-2:=[python_targets_pypy(-)?,python_targets_python2_7(-)?,python_targets_python3_5(-)?,python_targets_python3_6(-)?,python_targets_python3_7(-)?,-python_single_target_pypy(-),-python_single_target_python2_7(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-)]" have been masked.
!!! One of the following masked packages is required to complete your request:
- dev-lang/python-exec-9999::gentoo (masked by: EAPI 7)
- dev-lang/python-exec-2.4.6-r1::gentoo (masked by: EAPI 7)

The current version of portage supports EAPI '6'. You must upgrade to a
newer version of portage before EAPI masked packages can be installed.
(dependency required by "sys-apps/portage-2.3.76-r1::gentoo" [ebuild])
(dependency required by "portage" [argument])
For more information, see the MASKED PACKAGES section in the emerge
man page or refer to the Gentoo Handbook.
