Aha, I see. In this case... well, I don't think there's a solution
that's entirely satisfactory.
The closest thing I can think of, is that one is called libfooN, while
the other libfooN-nonfree, they conflict & replace each other, and both
provide the same filenames. So far, it's easy.
The hard part is making sure that dpkg-shlibdeps does the right thing,
and produces dependencies like libfooN (>= blah) | libfooN-nonfree (>=
blah). I'll leave this part as an excercise for the reader. >;)
