[erlang-questions] Stuff that breaks when you move it

to bypass this, cean's modified erl script uses this hack (using bin/erl,
that uses erlang/lib)

here=`which "$0"`
base=`dirname "$here"`/..
[ -z "$BASEDIR" ] && BASEDIR=`cd "$base"; pwd`
ROOTDIR="$BASEDIR/erlang"

it still allows to have several version installed, starting the one we
want, but allows to move the directory without breaking things.

regards.
