The GRASS libraries require certain environment variables to be set,
primarily GISBASE and GISRC. GISBASE is needs to contain the path to
the root of the GRASS installation. GISRC needs to contain the path to
a file which will hold various operating parameters (primarily the
database directory, location and mapset).

Look at the script etc/Init.sh in the GRASS installation for more
details.
