[GRASS-user] v.proj Not Working As Expected

[Rich Shepard]

   Trying to copy separate location/data into a common location (named
'Oregon') with grass-6.4svn. I set /usr4/grassbase/Oregon as pwd and start
grass64. At the command line I enter:

GRASS 6.4.0svn (Oregon):/usr4/grassbase/Oregon > v.proj in=highways
location=/usr4/grassbase/highways/ mapset=rbs

and immediately get this fatal error:

ERROR: Mapset <rbs> in input location </usr4/grassbase/highways/> not found

yet it is there. Same error if I specify mapset=PERMANENT.

   What have I done incorrectly?
