Please note that this seems to be a pretty antique GRASS GIS version...

Please use GRASS GIS 7:
http://grass.osgeo.org/download/software/linux/
--> Precompiled GRASS GIS 7.svn
  ---> Ubuntu

GRASS 7 comes with Large File Support, see
http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures#Libvector

Hope this helps,
