python2.7 pip install fails with SSLError

[Steven Smith]

I’m trying to update calendar-contacts-server to macOS 12.3. This requires installing a bunch of stuff with python2.7’s pip.

I’m hitting an SSLError at the command:

> /opt/local/bin/python2.7 -m pip install -I --user setuptools==18.5

Is there a way of pointing MacPorts python2.7 pip at a set of up-to-date CAs? [Say e.g. from curl-ca-bundle?]

Error:
