This might help someone who is trying to run the v.rast.stats (univariate statistics of raster values inside a vector area) in the GRASS 6.4 windows distribution. If the error message which appears when running v.rast.stats is "Cannot continue (problem adding columns)" it might be due to the v.db.addcol module not being correctly accessed by the script because it looks for it in the bin directory where it only finds the v.rast.stats.bat file (developers can correct me if I am wrong!). You can solve this by copying the v.db.addcol script that you find in the script directory in the bin directory. It worked for me, of course it is only a hack.
Cheers!
