Unmet compilation dependency: libsdl2-dev, perhaps libwayland-dev

[wnorfl]

I'm following the "FFmpeg CompilationGuide/Ubuntu". Ubuntu 14.04. The first step, "Get the Dependencies" generates an error in installing libsdl2-dev:

$ sudo apt-get install libsdl2-dev

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

I do realize that this may have nothing directly to do with FFmpeg. Nevertheless, suggestions?

Thank you for considering my question.

I see, just a version problem. libwayland's client, server, and cursor packages have gotten out ahead of libwayland itself (version 1.7.0 vs. 1.4.0). Hope I have not wasted your time.
