## You don't have an importable ssl module. You are most ##

## likely using Python 2.5, which did not include ssl ##

## support by default. In this state, we can not provide ##

## ssl certified downloads from PyPI. ##
|
|
## ##
|
|
## You can do one of 2 things: ##
|
|
## 1) Install this: https://pypi.python.org/pypi/ssl/ ##
|
|
## (It provides ssl support for older Pythons ) ##
|
|
## 2) Use the --insecure option to allow this insecurity ##
