[Koha] Where is /installer/install.pl

Hi, I installed koha 3.00.02.012, configured apache, but when I want to browse to intranet/cgi-bin/mainpage.pl or about.pl I am taken to /installer/install.pl. I Get "HTTP 404 - File not found" for it. Also, I thought if I create the 'koha' database, '#make install' was going to build all the tables and indexes for me!!! the Koha database is empty. -- Thank you, //Agron
