[GRASS-dev] libgrass_iostream build problem...

OK - here are the particular...and thanks again  folks for even looking at
this foo!!!

when the console output sez: "Will need at least 40.57G (43560695808)
space available in /home/cgn/tmp/ " that should not be a problem
whatsoever....there's 10x there available...

cgn at maps:~/tmp$ pwd

cgn at maps:~/tmp$ df -k .

So here's my region - the island of Hispanola, in UTM, using 30m ASTER
DEMs... (all this is just a warm-up for the inevitable hurricane and
subsequent flooding...)
