The variables in .grassrc are not automatically exported to your environment.
You can either set these environmental variables manually ( setenv CELL_HEIGHT
2666, etc., if you are running csh), or have them set automatically by
creating a .grass.cshrc file in your home directory with these variables
added to it (normally, copy your standard .cshrc to .grass.cshrc and edit it).
