Subject: ruby-sdl problem

Hi, I've been reading this introduction to rubysdl

  (http://www.oreillynet.com/pub/a/ruby/2007/12/04/creating-games-in-ruby.html)

and wanted to try it.

My problem is the following:

irb(main):001:0> require "rubygems"
=> true
irb(main):002:0> require "sdl"
=> true
irb(main):004:0> SDL::init(SDL::INIT_VIDEO)
=> nil
irb(main):005:0> screen = SDL::Screen.open(640,480,24,SDL::SWSURFACE)
=> #<SDL::Screen:0x7fba2ba87798>
irb(main):006:0> image = SDL::Surface.load("humans.png")
NoMethodError: private method `load' called for SDL::Surface:Class
        from (irb):5

How do I load an image?

Documentation extract:

SDL::Surface.load(filename)

    Load image into an surface and returns surface object. If image
format supports transparent color, colorkey is set into new surfafe.

    Supoorted formats are BMP, PNM (PPM/PGM/PBM), XPM, XCF, PCX, GIF,
JPEG, TIFF, TGA, PNG and LBM.

    Raises SDL::Error on failure

    You need SDL_image to use this method.
