    No .o or .hi files in depends/cpphs and I don't have a Cpphs under

    If I unregister cpphs from ghc, then run "scons" (after a "scons
clean") I get the following error...

ghc -i./src/compiler98 -idepends/cpphs -idepends/filepath -fwarn-missing-signatures 
-c src/compiler98/Front.lhs -o src/compiler98/Front.o

    Failed to load interface for `Language.Preprocessor.Unlit':
        Could not find module `Language.Preprocessor.Unlit':
          use -v to see a list of the files searched for
scons: *** [src/compiler98/Front.o] Error 1
scons: building terminated because of errors.
