You have a file called Prelude.hs containing a module Hugs.Prelude in
your current directory.  When Hugs starts, it loads Hugs.Prelude, which
it finds in the default path, and then attempts to load Prelude from
Prelude.hs (because . is at the front of the search path).  However this
file contains a module Hugs.Prelude, not the Prelude it was expecting,
and initialization fails.

The error message when Hugs finds a file to contain the wrong module
could be better, though.
