Google App Engine and Human API python lib - google-app-engine

Question

I am trying to use the Human Api Python client with GAE.
I created a appengine_config.py and followed all instructions as described in Third-party Libraries in Python 2.7 documentation for GAE
My appengine_config.py looks like:
"""This file is loaded when starting a new application instance."""
from google.appengine.ext import vendor
# Add any libraries installed in the "lib" folder.
vendor.add('lib')
My requirements.txt looks like so:
HumanAPI
... and installs correctly:
Downloading/unpacking HumanAPI (from -r requirements.txt (line 1))
Downloading humanapi-0.1.10.tar.gz
Running setup.py (path:/private/var/folders/yq/s_1v2vtn2sxbtw_gz00q1r5w0000gp/T/pip_build_jimmykane/HumanAPI/setup.py) egg_info for package HumanAPI
Downloading/unpacking requests>=0.13.2 (from HumanAPI->-r requirements.txt (line 1))
Downloading requests-2.6.0-py2.py3-none-any.whl (469kB): 469kB downloaded
Downloading/unpacking docopt==0.4.0 (from HumanAPI->-r requirements.txt (line 1))
Downloading docopt-0.4.0.tar.gz
Running setup.py (path:/private/var/folders/yq/s_1v2vtn2sxbtw_gz00q1r5w0000gp/T/pip_build_jimmykane/docopt/setup.py) egg_info for package docopt
Installing collected packages: HumanAPI, requests, docopt
Running setup.py install for HumanAPI
Running setup.py install for docopt
Successfully installed HumanAPI requests docopt
Cleaning up...
But when I try to import:
from humanapi import get_authorize_url, get_auth_session
I get:
ERROR 2015-03-27 13:18:05,023 wsgi.py:263]

Anyone to help me solving this dependancy thingy or guide me to what I am doing wrong?
Thanks
