What you need to do is put the program "sc_ver" in /usr/bin. You will need to be root. You can either copy it, or (better) create a symbolic link. To create symbolic link:
ln -s /path/to/shoutcast/sc_ver /usr/bin
Where /path/to/shoutcast is the path to wherever sc_ver is.
If you do this, then you start the program like any other - no ./ needed. The ./ just means the current directory - ie ./sc_ver means execute the sc_ver that is in the current directory.
I hope this helps
