That's really close, but I think you'll also need to get a pack in there to
make the label visible:

    require 'tk'
    TkLabel.new {
        text 'Hello, World!'
        pack
    }
    Tk.mainloop

You shouldn't (need to) modify the require statement to indicate a path. The
code as shown above should "just work" with the Windows installer. If it
doesn't, please give more info.
