Awesome, thanks much!
I did start running through, last night, updating the build.sh with updated package pointers, and started to build it myself off a fork.
I stopped once I hit an error with Bison not being installed, as it stopped the make process midway, and I didn't have time to finish wrapping up.
I was trying to self document the process as I went, but do you know of any other gotchas or requirements that might pop up as I go along in the future?
