By the way the best miner software for GS is this: https://github.com/siklon/cpuminer-gc3355
With your Raspberry you could try to install Minera it has every miners for GS built-in and a cool web dashboard to handle everything.
I highly suggest using Minera. It will be much easier to use and far less setup time.
Only if your wanting to learn about the programs and command, or more behind the scenes is it worth doing it on raspbian. And that is not a bad thing if you want this you will learn a lot more this way.
But most want the point/click start for ease of use.
