ego fails after 1.4 upgrade has simple fix

[bpaddock]

I just upgraded my container from 1.3 to 1.4 all went well until I rebooted and did

a eix-sync that called ego.  ego failed saying it could not find the module 'portage'.

The fix was simple enough once I figured it out, it should be added to the upgrade instructions.

Must make sure that python-3.7 is selected with eselect python.
Before doing that the removed 3.6 was still in the list.

Is that something that esleect python cleanup should have fixed?
I know I ran it.
