I'm not a Tk guy, but this works for me on 1.9.3p0 on Win7 32bit:

require 'tk'
require 'tkextlib/tile'

TkT = Tk::Tile

root = TkRoot.new { title 'Progressbar Demo' }
content = TkT::Frame.new(root) { padding '3 3 12 12' }.grid(:sticky =>
'nsew')
TkGrid.columnconfigure(root, 0, :weight => 1)
TkGrid.rowconfigure(root, 0, :weight => 1)

p = TkT::Progressbar.new(content) do
  orient 'horizontal'
  length 200;
  mode 'determinate'
end.grid(:column => 1, :row => 1, :sticky => 'we')

position = TkVariable.new
position.value = 20
p.variable = position

Tk.mainloop
