the latest version of the plugin doesn't work - it won't wipe the google analytics cookies - best to manually add the code as outlined here:

if you prefer a plugin version 1.4 here:

DOES work although there's no implied consent meaning you have to wait till people opt in before analytics starts working...
you only need to add the analytics code in the cookie control settings - and remember to add the ccAddAnalytics() callbacks!
