A similar (same?) question came up how to perform
http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=Cost_Allocation

Trying this:
r.cost input=cost_ras start_rast=source_ras output=costsurf nearest=cost_alloc

I got a different result. Input files from the example attached,
they were generated in the NC location.

Wrong usage at my end?
