cant go ant further after installing GNUnet
 

Actually i am new at Linux World. I wanted a P2P and i installed GNUnet-0.7.0b.tar.bz2 and also libextractor-0.5.11.tar.gz(while installing GNUnet it asked for libextractor). well i do have it installed but i can't go any further from here. How can i start from here? What should i do?
