raster maps and mapserver

[Alexia81]

Hi!
I took the mapserver demo1 with spearfish from grass.itc.it so i cannot have
any extents problems.

On my linux box, the application is ok except for raster data. When i select
the grass raster layer a white gif is generated without any error.

On my mac osx box the same demo works perfectly.

On both configurations i have grass60 without any library from previous
versions.

Thanks,
Alessia
