I noticed there's no package that depends on any binary package
generated by haskelldb-hdbc which is not strictly related to the
package, so maybe 3 is not a very bad option.  I've made a haskell
scripts to check this (sorry for not being Shell or Perl):

-- base
import Control.Monad (foldM)
import Data.List (isPrefixOf)
import System.Environment (getArgs)

-- process
import System.Process (readProcess)

main :: IO ()
main = getArgs >>= rdepends [] . head >>= putStr . unlines

rdepends :: [String] -> String -> IO [String]
rdepends actual package
  = readProcess "apt-cache" ["rdepends", package] ""
    >>= foldM rdepends (package : actual)
      . filter (not . flip elem actual)
      . map (drop 2)
      . filter (isPrefixOf "  ")
      . lines

Running it:
