 I appreciate your help to correct the following error when I start GRASS on my Mac.:

WELCOME TO GRASS              Version 6.4.2         2012

   1) Have at your side all available GRASS tutorials

   2) When working on your location, the following materials
      are extremely useful:
      - A topo map of your area
      - Current catalog of available computer maps

   3) Check the GRASS webpages for feedback mailinglists and more:
