ROS for BeagleBoard-xM using Angstrom


For a couple of weeks I have been trying to get ROS installed on my BBxM using Angstrom 2.6.32 kernel. All I have found so far is that ROS is NOT supported on the BBxM, which is basically not true because it is available on Ubuntu for BB(xM). So my question is: why would it not be for Angstrom and BBxM ?
