Do you have ca-certificates installed?

It's been a long while since I rebuilt Python from the Git source. I tried for the first time the other day. Everything passed except testpoplib and testasyncio. The former just runs and runs and runs. Here's the first traceback I encounter when executing ./python Lib/test/testpoplib.py:

Not sure what was wrong with testasyncio. I ran it in isolation and it passed. Thx, Skip
