Looking at this again, the installed version of portage says (in the
output quoted in your initial post) that it supports EAPI 6, which is
also used by the python-exec-2.4.6 ebuild (not in the tree anymore, the
one using EAPI 7 is 2.4.6-r1). So you could give the 2.4.6 ebuild a try:

https://gitweb.gentoo.org/repo/gentoo.git/plain/dev-lang/python-exec/python-exec-2.4.6.ebuild?id=20664dd65ec565233f460b94efc0337249b84550

Hopefully this will allow you to upgrade portage, unless there are more
dependencies of portage in similar situations. If this ebuild is not
enough, any chance you have another machine where you could do the
date-based checkout and then copy the entire portage tree?
