[Koha] Koha 2.0.2 Install problem

Hi All... I decided to have a go at installing Koha 2.0.2 on to a fresh install of Debian 3.0 (Sarge). The install all happened as it was supposed to and I choose defaults for everything. My problem is that when I go to http://server/koha or http://server/opac I get page not found errors. I'm thinking that I need to edited the httpd.conf file to add something, but I'm not sure what. Any ideas? Thanks Michael
