I've not long had my pi I'm a very basic user but I think I'm able to follow instructions... and still I can't get my PiGlow to work

pi@retropie ~/PiGlow $ uname -a
Linux retropie 4.1.9-v7+ #819 SMP PREEMPT Thu Oct 1 20:47:52 BST 2015 armv7l GNU/Linux

after much digging around I read to install Gadgetoid fix

git clone https://github.com/Gadgetoid/PiGlow
cd PiGlow
sudo python setup.py install
