Fails with 403 error on any command that queries PyPI

[elirnm]

Yolk is failing with "HTTP Error 403: Must access using HTTPS instead of HTTP" when it runs with any command which queries PyPI. This started just in the last few days.

This is likely a support lib being out of date, but the error message is less than helpful.

Old yolk 0.8.7:

yolk -U
HTTP Error 403: Must access using HTTPS instead of HTTP

After updating yolk in fink:

yolk -U
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)>

fink list yolk3k
