Could not find module "Graphics.Gnuplot.Execute"

[guest]

Trying to run Demo.hs. After removing the "import qualified Paths_gnuplot as Path" and any places that use it to fix (http://trac.haskell.org/gnuplot/ticket/2) - I am getting the error:

Graphics\Gnuplot\Advanced.hs:80:18:
    Could not find module `Graphics.Gnuplot.Execute':
      It is a member of the hidden package `gnuplot-0.4.2'.
      it is a hidden module in the package `gnuplot-0.4.2'
      it is a hidden module in the package `gnuplot-0.5'
      Use -v to see a list of the files searched for.
Failed, modules loaded: none.

Using Windows 7 with Haskell platform, and gnuplot 4.6rc1 for windows.

This is really frustrating...
