[GRASS-user] problem installing addons in grass7

[Agustin Diez Castillo]

Dear list,
I gues this is basic stuff but I can't find a solution to install install.
When I try to install some addons in grass7, it advise me to install 'install' first. 
g.extension -l svnurl=https://svn.osgeo.org/grass/grass-addons/grass7 prefix=$GRASS_ADDON_PATH
ERROR: install required. Please install 'install' first.
Is that related to $GRASS_ADDON_PATH ?
I'm on mac intel.
Thanks
