postrm/postinst phases fail with this error:
ModuleNotFoundError: No module named 'encodings'
debug: operror-type: ModuleNotFoundError
debug: operror-value: No module named 'encodings'
Steps to Reproduce:
1. Set pypy3 as system interpreter
2. Upgrade dev-python/pypy3 from 0/pypy38-pp73 to 0/pypy39-pp73
I think this is quite well known but not sure we can do much about it.
mgorny referenced it in his pypy post to the gentoo-dev ML a while ago: https://marc.info/?l=gentoo-dev&m=161469756208830&w=2.
