I've tried installing from source, what gives?

Reproduce the failure with `pip install unirest`, then inspect the dependency paths shown in the traceback, especially `poster/setup.py` and `poster/streaminghttp.py`. Confirm which Python versions this project intends to support before changing anything; done should mean the supported installation path no longer fails. The issue has no recent response, so check project history for current compatibility guidance first.
