It was going great until it stopped working. It sent me to the website to download the newest version (after I already emerged icecast through portage). So I downloaded it, and then it told me to "cd icecast-1.3.12/" as the very next step here -
http://www.gnuware.com/icecast/sect_03_02.html. If you hit previous in the bottom left, it'll go to the download instructions I followed.
It was the .tar file I downloaded, but it didn't tell me to do anything with it. So on the next page, the proposed icecast directory doesn't exist, anyone know what's up?
