sudo will reset the environment unless -E is used (and the "setenv"
option is enabled in the sudoers file).

Also, the loader will typically clear any variables related to dynamic
loading (LD_LIBRARY_PATH etc) when running a setuid/setgid binary such
as sudo. That's why $GISBASE/etc/grass-run.sh exists: to run a command
with LD_LIBRARY_PATH restored from $GRASS_LD_LIBRARY_PATH (this is
necessary when running a GRASS command in an xterm, as the xterm
binary may be setuid/setgid).
