Checking to to see if a distribution has the packages:

In Mythbuntu 14.04 (I really have a box with that loaded),
these aren't found:

$ sudo apt-cache search python-requests-cache
$ sudo apt-cache search python-future

I chose to use pip to get them. And did the same to get an
up-to-date urllib3.

This what I've been testing with on the 14.04 box:

$ pip show future requests requests-cache urllib3
