For what it's worth, I tried this procedure and documented it

https://github.com/sagarbehere/beaglebone-xenomai/blob/master/beaglebone-xenomai-debian.md

I used the for-upstream/3.8 branch, but it should be similar for the 
ipipe-3.8 branch.

If you improve upon the procedure, please let me know and I will update 
the document accordingly, or fork it and send me a pull request :)
