Mac osx 10.4

I tried to follow a tutorial on how to install mediatomb (so as to stream music/pics to ps3) and in the process got a parsing code and that the config.xml ended abruptly. Now when I try to open mediatomb via the “terminal” it gives me this error.

Question: how exactly do I enter the command to uninstall/remove mediatomb so I can reload it?

Thanks,

Curt

P.S. I’m green at writing code!!!
