I've gone back to the same pull I built/installed and ran on the 
armhf/jessie, reran configure for uspace, and after well over a gig of 
dependencies were installed, its building again. No clue if it will 
actually work.

But where do I find one of your tut's on building rt-preempt kernels? I 
thought I'd found it and bookmarked it but can't find it in my bookmarks 
now.

Cheers, Gene Heskett
