Looking at the error, sdl isn't the only thing you're missing. You're also missing libavutil, libswscale, libavcodec and libavformat. Those are libraries that are typically provided by ffmpeg. If you're missing them, then it's most likely you don't have ffmpeg installed correctly.

Please install ffmpeg. There's a link to detailed instructions in the README.

On Ubuntu 15.10 you also need:

sudo apt-get install libsdl1.2-dev

I had installed libsdl2-dev, but it's not the one.
