[GRASS-user] Problems while installing addons. Can't find gis.h

Hi List,
I was trying to install the v.vect.stats add on, but i got some problems, which I wasn't able to fix with the help of the existing mailing list.

First of all, I tried g.extension extension=v.vect.stats.

It couldn't find any add on, because the script is using a wrong url to svn:
svn: URL 'https://svn.osgeo.org/grass/grass-addons/vector/v.vect.stats’ doesn't exist.
There is obviously a ../grass6/.. missing.
I changed the g.extension script and modified the URL. Than the package was found but after that there was another error. gis.h could't be found.

I checked whether the module exists, and it does.

I also tried to install by myself with make and I had the same probs.

How can I fix this problem? Does anyone have an idea?

Thanks for your help!
Steffen
Ps: I'm using grass 6.4.1 with ubuntu 11.11 32bit, if it matters.

Hi,

the g.extension module(s) only starts to begin to work for end-
users who installed from a package with the upcoming 6.4.2, due in
a few days. you'll need the grass-dev package installed too.

if you can't wait, you can try to compile 6.4.2rc3 from source.
