Memetracker: Need to Implement still

We have the Memetracker module installed. Yet in our list of results, the 'Need to Implement still.' message appears next to every result returned.

Also our result list order is not affected by anything we can do.

Can anyone help us resolve this problem?

We have the following installed on our server:
OS: Fedora 8
Drupal Version: 6.6
Memetracker version 6.x-1.1-alpha6
Python version: 2.5.1
