Difference between constraint and dependency

I'm not sure I'm clear on how (technically) constraints are different from dependencies. Both of them restrict the project and hinder its progress. I appreciate a thorough discussion on the topic.

A constraint is a boundary within which you must conduct your project.  You might have to use certain staff, or you might have a limited amount of time, or you may have to use a certain technology, or you might have to be located within 5 miles of a site.  Those are all constraints.

A dependency is a specific thing that must be done (or started) before another thing can be started (or done).  It's a sequencing thing.  You must select a project manager before a project management plan can be created. You must design a boat before you can build it.  You must have a customer before you can make a sale. You must have a ticket before you can see a movie. Those are all dependencies.

You could view a dependency as a constraint, but doing so probably blurs both.
