OK digging into this more I think the problem is the images are too old:

  bdb7b450deaa / # ls -l usr/lib/python-exec/python-exec2
  -rwxr-xr-x 1 root root 1461 Dec  8  2016 usr/lib/python-exec/python-exec2

To have a proper Gentoo environment you need to take the latest stage3,
sync the portage tree and update all the tools. It's a little odd
because the hub claims the last build was 18 hours ago but the portage
is still older than mine:

  13:37:45 [alex@danny:~/tmp] 1 $ ls -l /usr/lib/python-exec/python-exec2
  -rwxr-xr-x 1 root root 2302 Sep 10 14:09 /usr/lib/python-exec/python-exec2*

I'll have a dig into the stage tarballs.
