Isn’t that a fairly general problem with openssl and various sites like github,
pypi etc.?
I am getting the same error (on 10.10 as well) when trying to manually download
the
file with fink’s wget, while the system curl and ‘wget —no-check-certificate’
find it.
I actually thought that was a real issue with the certificates on those sites,
but since
nothing has happened on that side in months, it may be a bug, but definitely
somewhere
further up with urllib/openssl, not really mpl’s problem.
Cheers,
Derek
