[gentoo-portage-dev] Portage upgrade from 2.3.62 to 2.3.65 fails

[Joakim Tjernlund]

Trying to upgrade portage in an older embedded target I get:
When upgrading from old 2.3.62 
    >>> Merging sys-apps/portage-2.3.65 to /
    /usr/bin/python3.4: Error while finding spec for 'portage._compat_upgrade.default_locations' (<class 'ImportError'>: No module named 'portage._compat_upgrade')
     * ERROR: sys-apps/portage-2.3.65::tmv3-target-overlay failed (preinst phase):
     *   (no error message)
     *
     * Call stack:
     *     ebuild.sh, line 133:  Called pkg_preinst
     *   environment, line 3193:  Called die
     * The specific snippet of code:
     *       env -u DISTDIR -u PORTAGE_OVERRIDE_EPREFIX -u PORTAGE_REPOSITORIES -u PORTDIR -u PORTDIR_OVERLAY PYTHONPATH="${D%/}${PYTHON_SITEDIR}${PYTHONPATH:+:${PYTHONPATH}}" "${PYTHON}" -m portage._compat_upgrade.default_locations || die;
     *

Not a python expert but isn't portage trying to use a new function in portage(portage._compat_upgrade.default_locations) before
it is installed?

How should I resolve this?

That's a strange failure, since this code from the ebuild should die
earlier with a "No such directory" error if something is wrong:

Apparently your overlay has modified the portage-2.3.65 ebuild to add
python3_4 to PYTHON_COMPAT. Check if this file exists (it's supposed
to but the error seems to indicate that python didn't find it):

/var/tmp/portage/sys-apps/portage-2.3.65/image/usr/lib*/python3.4/site-packages/portage/_compat_upgrade/default_locations.py

Thanks,
Zac
