[Haskell-beginners] How to import the Data.Char library in Hugs?

My apologies if this is an extremely elementary question, but I am
having difficulties in importing the Data.Char library in Hugs.

In GHCi, the command "import Data.Char" works correctly, as follows:

--8<---------------cut here---------------start------------->8---
GHCi, version 6.10.3: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer ... linking ... done.
Loading package base ... linking ... done.

However, in Hugs, the same command fails with an error, as follows:

Does anybody know how to import the Data.Char library in Hugs?
