I am trying to draw a simple pixel with gtk/haskell.  This is the code, but
I get an error.

GHC 6.12.3? with the most recent gtk library.


# ghc --make SimpleCells.hs
[1 of 1] Compiling Main             ( SimpleCells.hs, SimpleCells.o )

Graphics\UI\Gtk\Misc\DrawingArea.chs:22:10: Not in scope: `gcNew'


import Graphics.UI.Gtk

renderScene d ev = do
dw  <- widgetGetDrawWindow d
(w,h) <- widgetGetSize d
gc    <- gcNew dw
return True

main = do
window  <- windowNew
drawing <- drawingAreaNew
onExpose drawing (renderScene drawing)
 window `onDestroy` mainQuit
windowSetDefaultSize window 800 600
windowSetPosition window WinPosCenter
widgetShowAll window
