This package is a companion to the node-sdl package. It was built so the OpenGL bindings for SDL could remain separate from the SDL library.
If you are looking for something else try the node-webgl project.
This package depends on node-sdl and OpenGL/SDL libraries being present on the target system. The following should get SDL installed on Ubunutu:
sudo apt-get install libsdl-mixer1.2-dev libsdl-image1.2-dev libsdl-ttf2.0-dev
