Surely it should still be possible to accurately transcribe upstream 
dependencies into the debian/control file?

I was listing all the packages that apt thinks depend on ruby. I didn't 
type "yes" and actually remove ruby, I'm not a *complete* idiot. :)

You'll notice that these are cached gems; they were most likely created 
by running `gem pristine` to fix the earlier issues. I have never

Everything *not* installed by some debian package? That sounds painful. 
Is there a tool for that?

knock-on breakage.
