Python3 support?

In Python3.4, I run
$ pip install unirest
I get the following error:

SyntaxError: invalid syntax

PS: I'm running Windows 8.1, although this looks like a problem in python2 vs python3 syntax.

Reproduce the failure with `pip install unirest` under Python 3.4, then inspect setup.py and the poster dependency, especially poster/streaminghttp.py where the Python 2 print syntax fails. Done means the package installs successfully on Python 3.4 without this SyntaxError.
