On second reading, ghc asks for profiling libraries for haskell98, that would 
mean you should look for Char.p_hi. If there are no *.p_hi files in the 
folder, that library wasn't built for profiling and you should do that then,

runghc ./Setup.hs configure -p
runghc ./Setup.hs build
runghc ./Setup.hs haddock
runghc ./Setup.hs install

Hope this helps,
