[Koha] Need help with installation

Hi, I am very interested in Koha and wish to install and use it and hopefuly in the fullness of time contribute to the end product. However, at the moment I am a newbie to installing perl modules and would welcome any help to getting the circulation telnet program working. I get the error cant find cdk.pm. I have the koha and opac web server side of things working and I've installed and created the tables etc needed in MySQL. this cdk problem looks like its the last hurdle. Thanks in advance Brad Joyce bradj@coffsccs.nsw.edu.au
