Can you grab the non SVN version and check the install instructions that come with that download?
I'm using the download version, perhaps the SVN is broken? Radiogetswild uses this module as well. Over at dev.5mind.co.uk/index.php is a forum with a lot of info in the, perhaps you could try asking / digging over there?
