Pirate radio mopidy config issue

ive just installed the mopidy software and im getting errors in 3 places when I start it:

  1. failed to load extension iris: no module names 'handlers;

  2. my conf for spotify is being ignored due to config errors, yet it is entered correctly, like:

enabled = true
username = myuser ; must be set
password = mypass ; must be set
client_id = ; must be set
client_secret = ; must be set

  1. when I browse to localhost:6680 I get the expected web page, but no clients are shown

Any help is appreciated as Im new to the Pi.
