Install from pip feature

Made this small modification to allow for installation from pip
Ah, cheers for the info. No problem with using epel. 

I tend to include the [epel](https://forge.puppetlabs.com/stahnma/epel) module to do this. If you could add then it looks like this is good to good. Thanks again. I'll think about flipping this to the default install path in a major revision maybe.
