[GRASS-user] Warnings installing some r.stream addons

[César Augusto Ramírez Franco]

Hello dear list

I'm trying to install all the r.stream addons, but some of them are
printing warnings, I'm using grass 7.0.3 from the ubuntugis PPA in Ubuntu
14.04.3

The output is:

patient)...

Should this warnings be ignored? Or should they be taken into account in
some way when using them?

Thanks in advance
