Dear Sir or Madam,

as part of my master's thesis I would like to use the tool  
r.green.hydro with all its functions. After I've completed all the  
steps of your detailed online installation guide, Grass-Gis will  
create a field called "Energy." The functions of this field are grayed  
out and can not be executed. After entering the r.green.install -x  
command, you also receive the message that the python libraries  
numexpr and scipy are not available. After I installed these manually,  
the message did not occur anymore, but the functions in "Energy" were  
also not executable and still written in gray.
Additionally, when you load Grass-GIS into the black console, you see  
the following message:

Details: Can not find the executable r.green.hydro ....
r.green.hydro ...: Unable to fetch interface description for command  
'r.green.hydro ....' "

Since I would benefit greatly from the use of the tool for my  
explorations, I would be very grateful if you could help me with my  

With best regards
Annemarie Pfeiffer

Mit freundlichen Grüßen
Annemarie Pfeiffer
