Unable to use against opensource Mist

[hundredacres]

Trying to use the client against my opensource install of Mist and getting the following errors

Traceback (most recent call last): File "/bin/mist", line 1249, in <module> main() File "/bin/mist", line 1246, in main user_info() File "/usr/lib/python2.7/site-packages/mistcommand/helpers/login.py", line 106, in user_info client = authenticate() File "/usr/lib/python2.7/site-packages/mistcommand/helpers/login.py", line 101, in authenticate client = parse_config() File "/usr/lib/python2.7/site-packages/mistcommand/helpers/login.py", line 41, in parse_config api_token=api_token) File "/usr/lib/python2.7/site-packages/mistclient/__init__.py", line 47, in __init__ self.__authenticate() File "/usr/lib/python2.7/site-packages/mistclient/__init__.py", line 77, in __authenticate response = req.post().json() File "/usr/lib/python2.7/site-packages/mistclient/helpers.py", line 58, in post return self.response(resp) File "/usr/lib/python2.7/site-packages/mistclient/helpers.py", line 53, in response raise Exception(resp.content) Exception: Not authorized

I've updated the ~/.mist file mist_uri param to point to my local install, but I'm not sure what to do next?
