Description
LineBuffering is a constructor, and System.IO definitely does export it. A more helpful error message might be
`LineBuffering' is a constructor in the data type `BufferMode`,
to import it use
import System.IO (BufferMode(LineBuffering))
or
import System.IO (BufferMode(..))
(adapted from a suggestion by John Launchbury)
