Awesome! Only... I've got a problem here... Sorry to be so nooby, but
here's what's going on:

GRASS 6.4.2RC1 (ETRS89_ll):~ > g.extension extension=r.univar.zonal

 Stop.

I can't find any Multi.make either, except for in my GRASS 7 sources. I'm
actually wanting to work in GRASS 6, but even if I try the same command in
GRASS 7, another problem happens. Although I did swap the repository for
it, that might be causing the problem (?)? Here it is:

GRASS 7.0.svn (ETRS89_ll at Niedersachsen_Test):~ > g.extension

I tried hardwiring my top include folder (/usr/local/grass-7.0.svn/) where
the makefile seemed to be looking for Multi.make into the makefile, but
that didn't help either. Any ideas?

Do you mean just taking the line in v.rast.stats2 with


BASECOLS="n min max range mean stddev variance cf_var sum"

and removing everything except for sum? Unfortunately, my knowledge of bash
scripting limits me here, I'd just try it out, but since I can't get the
extension installed yet anyway I figured I'd ask.

Thanks a lot!
