If you're using cdbs and r-cran.mk in debian/rules, you can add
Depends: ${R:Depends} to debian/control to pick up the current binary
dependency.  I've migrated almost all of my packages over and it makes
life easier.

Probably down the road it'd be good to create some lintian checks for
things like this dependency.  (The holy grail would be to verify build
dependencies and binary dependencies against the upstream
DESCRIPTION.)
