Not exactly what you're asking for, but debian has a package named Deborphan. It's a simple script that checks for packages installed as dependencies, that are no longer being used due to upgrades or removals. It generates a simple list, and leaves it to you to remove anything, in case you have something built from source relying on it, or some other need for them. I run it once a month or so on my machines, just to clean up a bit.
