Is /opt/grass/scripts set up in GRASS_ADDON_PATH, and
  export GRASS_ADDON_PATH=/opt/grass/scripts
set up in ~/.bashrc ?

(Scripts run in two passes, the first will start from the pwd,
but if that's not in the $PATH then the second g.parser pass
won't be able to find itself, and you get a not-very-helpful
error message.)


just a guess,
