Older python 2.7 setup

For python 2 the preferred version is 2.7.9+ as it contains a functional ssl module.

In testing the Redhat patched python version 2.7.8 works without modification.

This error can occur if you are using a python < 2.7.9 with an unpatched ssl module:

InsecurePlatformWarning: A true SSLContext object is not
available. This prevents urllib3 from configuring SSL appropriately and 
may cause certain SSL connections to fail. For more information, see 
https://urllib3.readthedocs.org/en/latest  
/security.html#insecureplatformwarning.

Further more it can think invalid certificates are valid.

Patching your python ssl

There is this guide to fix the ssl module: https://urllib3.readthedocs.io/en/latest/user-guide.html#ssl-py2, but in practice I have seen this fail to install. There are also recommendations online to run pip install pyopenssl ndg-httpsclient pyasn1, these have also failed for me. root may be required to install additional dependancies needed by these fixes.
