I know what you mean, but that's poorly worded.  Translations, for example,
don't contain any literal portion of the original, but are paradigm cases
of derivative works.

> Dependency alone does not constitute derivation.

Just so.  A classic instance is the C Answer Book, which contains answers
to the problems in K&R.  Although it absolutely depends on K&R for its
meaning, it is a completely independent work from the copyright standpoint.
