> What am I missing?

That's happened to me when my build fail midway, usually due to lack of disk 
space, and after freeing some and restarting it, that would happen. The reason 
is probably a bug in debian/rules' dependencies. If that was the case for you, 
you could restart the build with enough space and it should be fine.

Cheers,
Emilio
