help with an intriguing problem

Hi! the ghc compiler keeps complaing " can't find module 'Char', perhaps you haven't installed the profiling libraries for package haskell98?". but actually I did install it, and i checked with ghc -v , it is right there: "wired-in package haskell98 mapped to haskell98-1.0.1.0", and Char.hi is right there in the folder haskell98-1.0.1.0.. can't figure out why it happened.. anyone please ?
