I did install r.viewshed (it is located in ~/.grass6/addons/), and the
full path does appear in $PATH.
I am executing the Python script from outside of GRASS. Is this
normal? I am hoping for some advice on this. The intent is to liberate
some software (naturalcapitalproject.org) from ArcGIS for users on
When I start GRASS (in text mode) it says "Welcome to GRASS 6.4.2 (2012)."
