No you need also do init opengl after creating the context, here's how I 
am (was) doing it:

----------
static this() {
     DerelictSDL.load();
     DerelictGL.load();
}

void main() {
     writefln("main");
     if(SDL_Init(SDL_INIT_VIDEO)) {
         writefln("error: SDL_INIT_VIDEO");
         return;
     } else {
         writefln("no error (SDL_INIT_VIDEO)");
     }

     SDL_WM_SetCaption("titel", "nirgends");
     SDL_GL_SetAttribute(SDL_GL_BUFFER_SIZE, 16);
     SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 24);
     SDL_GL_SetAttribute(SDL_GL_STENCIL_SIZE, 0);
     SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
     //SDL_SetVideoMode(1000, 800, 32, SDL_OPENGL | SDL_RESIZABLE);
     SDL_SetVideoMode(1000, 800, 32, SDL_OPENGL);

     DerelictGL.loadModernVersions(GLVersion.GL30);
     DerelictGL.loadExtendedVersions();
     //DerelictGL.loadExtensions();


     // rendering goes here
}
