I got XDarwin and window manager working just fine. But when I try to run most of the application nothing happens and the terminal displays "zsh: command not found: xfm" - (this particular message appears when trying to run X File Manager). Some apps work though like the VI editor, but Xemacs outputs the same error message.

Also, whats .Xauthority? Should I create this file? Because I always get an error message saying that command or file name not found.
