[GRASS-user] Script i.histo.match

[PrusovaM at email.cz]

Hi everybody,

I have problem with i.histo.match.py in GRASS on Ubuntu. 
I have downloaded i.histo.match. py from 
https://svn.osgeo.org/grass/grass-addons/grass7/imagery/i.histo.match/
I tried to run the script by command: python i.histo.match.py, but it doesn'
t work.
I have GRASS 6.4.1. and error messsage is:

GRASS 6.4.1 (barvy):~ > python Stažené/i.histo.match.py

I search something about this problem and I find information about 
GRASS 7 and their new modules for python. I install GRASS 7, but this 
version gives error message:
