This isn't quite what Hugs needs.
Hugs needs functionality equivalent to dl_open on unix.
>From memory and with some simplification:

  handle dl_open(char*) loads a shared library file
  dl_lookup(handle,char*) looks up a name in a loaded shared library
  dl_close(handle) closes a shared library

Loading has to be explicit because it is done in response to the Hugs user
loading a Haskell file that requires a shared library.
