Yes. I meant ~/.grassrc6. Possibly I am lagging behind for some years
as I used GRASS 6.3.old there :). Now I am switching to GRASS 6.4 for my
cluster calculations and have to solve this problem.

So indeed I should modify
## use TMPDIR if it exists, otherwise /tmp
#tmp=${TMPDIR-/tmp}
#tmp="$tmp/grass6-$USER-$GIS_LOCK"
tmp=/tmp/grass6-$USER-$GIS_LOCK
(umask 077 && mkdir "$tmp") || {
    echo "Cannot create temporary directory! Exiting." 1>&2
    exit 1
}
GISRC="$tmp/gisrc"
export GISRC

Or no modifications needed at all? Mhh, probably I am really confusing things
and everything just works out of the box. Will test the next days.
