Hello...are you looking for someone to put in the work to set up Adafruit_BBIO on the newer images or are you trying to get someone to learn how to compile it so it can be of some use?

P.S. If you are rearranging source in C/C++ for the actual library, I will need time and I do not know of how much time is allowed before another person would/should take over. Anyway, any relative info. can be sent back to me on this link. I will keep it up for a couple of months and check back.
