Apps :: Installing PodNova

Hi, I just downloaded a podcast client PodNova as a tar.gz file (PodNova-2.2-Gnu_Linux.tar.gz). Can someone help me install it on DSL 3.0.1? I have used DSL for over half a year now but havent quite figured out how to install a program that is not part of MyDSL repository. Would appreciate any help on this. Thanks.
