For those who may stumble across this post in the future...
Still no luck with this project. I did find a newer version of the RGA library distribution (an_r01an2162ej0200) - and this version includes a "kpitgcc" folder.
However, the instructions look to have been written by an intern who didn't speak English - and they reference folders that don't exist. I'm trying a number of trial-and-error attempts, but I'm not optimistic.
