I've emailed with Laura about r.terracost and she would be happy to have someone convert the make file to work with grass6.

the % memory but it doesn't seem to help...
does it work for a smaller region or coarser resolution? for example try
changing it from 3 to 30m res.
ie can you determine if is it a 64bit computational error or an out-of-
resources error? (does r.cost work for the spearfish DEM on your system?)
I can't answer why memory problems would be an issue, but that doesn't
mean they aren't! Large mem grass is still untested territory in many
places, maybe you have discovered something new.
Did r.terracost work? How does that compare to r.cost? (if it's good,
I'm thinking maybe Laura would allow us to merge it in CVS as a
companion to r.terraflow, or package as a GEM)
Or does that use GRASS 5 sites as starting/end points and need porting?

This would be a great asset to grass6 -- I know several people who would
directly benefit from this!
cheers,
