[GRASS-dev] R.terraflow crashing on Mac

[Michael Barton]

I tried to run r.terrraflow on my Mac Intel last night and it crashed. This
is a version I compiled from the cvs on 23 January. Other recent versions
seem to work fine on the FC6 and FC4 workstations in my lab. I¹m copying the
error below in case anyone has a clue. (FWIW, the warning about
elevation_dem being found in multiple mapsets is both annoying and
misleading as my working mapset was indeed PERMANENT. This now happens with
multiple modules and I don¹t remember it appearing as often before).
