Here is the mapfile we use to generate a WMS scalebar layer for GeoMoose.

Another approach is to look at GeoMoose v2.4 and see where the scale_line object is used in the JavaScript.  It basically just configures the OpenLayers scalebar.  The advantage of this approach is that it can support the ground distance instead of just the map distance by including
