4)wget http://ck.kolivas.org/apps/cgminer/4.0/cgminer-4.0.0.tar.bz2

5)tar xvf cgminer-4.0.0.tar.bz2

6)cd cgminer-4.0.0


(THE PATCH 0.2.2 with a pendrive download to R.pi directory Pi
open the folder and copy it into the folder contents cgminer-4.0.0)

7)patch -p1 < 2786526d9f1acb7bd903ece3c822c2c9203aa0b7.patch
