error when installing some package but its actualy existing example django-ajax-filtered-fields==0.5
Downloading/unpacking django-aja
Inspecting the logs reveals the following line:
less .pip/pip.log
Could not fetch URL https://pypi.python.org/simple/WSGIUtils/: connection error: [Errno1] _ssl.c:493: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
In an earlier version of the comment I attributed this behaviour to https://pypi.python.org, but this is not the issue, since I can contact this site (from another computer!) with firefox and all certificates are OK. So this is probably a problem of some installations of pip---I encounter it unter SLES 11 which has (among other things) the "oldstable" openssl-0.9.8.
