Another update, I'm now running my RPi with Starminer which was recommended by  Scynthetic at the Litecoin forum, https://litecointalk.org/index.php?topic=19129.0
Starminer was designed with RPI in mind. Using the latest version 27 June, works good with G-Blade and easy to install and use. After booting RPi up installed wireless with sudo wicd-curses. Used the WebUI to setup, startup, passwords and config info are in Starminer Wiki. Took less than 20 minutes to set up after downloading and reading Wiki.
