for the PNG driver, when you do "d.mon start=PNG", does it say:
"PNG: GRASS_TRUECOLOR status: TRUE"

?

to turn it on, you need to do:
export GRASS_TRUECOLOR=TRUE

These both currently fail by the way -- they probably shouldn't:
GRASS_TRUECOLOR=1
GRASS_TRUECOLOR=true

Now we don't have GD to worry about, should GRASS_TRUECOLOR be set to 
TRUE by default?
