For some mac os x user, this might not solve the problem since the older version of pyOpenSSL never get uninstall. The way to solve it is to download the gz file from PyPI a link. Then unzip the compressed file. Navigate into it and then run the following command

sudo python setup.py install

Then pyOpenSSL is correctly updated.
