What about my example from Rails?  If one develops an app with one egg, and
that egg gets a backwards-incompatible update to itself, while the Chicken
release remains the same, you must have a way to stick that old egg on your
brand new server you want to deploy the old app on.

* The chicken versions it is known to work with
* The dependencies and their exact version

If a dependency gets a new release, you can only get that new dependency
working with the egg if the egg gets an update in its meta file and a new
release is made of the egg.

As described above.
