You said you installed fatty in the cgi-bin, but neither of the above are the cgi-bin. The root may contain a cgi-bin, but it's the cgi-bin and not the root where the files need to be uploaded.
Email your FTP info to me and I'll take a look...Something just doesn't sound right.
Do you hve any other perl/cgi files installed and running on this host? They may not have cgi configured properly.
