Having not used the script I would suggest a couple things:

1. check your region: kriging requires A LOT of matrix inversions, and thus 
becomes memory limited with large regions. 

2. you might try the commands one at a time in order to pin down the errors

Here is a link to a kriging example using grass vector data as the input, with 
R+GSTAT (not sure what v.surf.krige uses ...)
