[GRASS-user] add-ons install

[Szabó Balázs]

Hi list!

How it is possible install add-ons on ubuntu karmic koala?

I downloaded Hydrofoss from add-ons svn repository, and according to the
addons wiki page typed the #make MODULE_TOPDIR=/usr/lib/grass64/ 
but it returned with this error message: make: *** No rule to make
target `/usr/lib/grass64/include/Make/Dir.make'.  Stop.

What should be the solution? (I use the latest svn grass 7.0)

Thanks.
