The error was on my system. After trying several things (many thanks to Steve Jaffe at this point, who gave not up on me :)) I decided to make a reinstall of my system. I reinstalled the compiler and build R with gcc 4.8.1. I was then able to successfully install my package with the suggested configuration below.
Thanks to all for helping me out here.
