Try "python check_3d.py" or copy the script under the "scripts" directory in 
your local grass installation (somethin' lke 
"/usr/local/grass-6.4.0svn/scripts").

A, ok! You already did that.

Better not to use sudo (as a general advice). The script needs to be made 
executable for your user-name, i.e.:

sudo chown hanlie:hanlie  v.check3d
