X11 telling me "Newer software allready exists on this computer"
I can't install Ardour2.1 for Mac OS X (i run 10.4.11 on Intel), because it tells me to install X11 before running the app.
I downloaded X11 from apple.com, but X11 installation tells me "You cannot install X11 on this volume. Newer Software already exists on your computer".
What is this "Newer Software"? I'm stuck =/
