I am a totally new user to haskell and hugs. I am working on Mac OS X 10.4.7(intel), and compile the hugs src myself(configure, make, make install), and than generate the hugs under /usr/local/bin and /usr/local/lib/hugs normally. When I launch hugs, it does not display "reading Preclude.hs" or like as the book describes. When I am running some simple programs from the book "Haskell: The Craft of Functional Programming", the error occurs to say cannot find 'ord', 'chr', or 'fromInt' and so on what I think should be defined in Preclude. But 'max' and 'min' goes correctly. I try to 'import Preclude' at the start line in the program, it says cannot find module Preclude. And I tried other packages, also cannot be found. Generally, I can't find where to load Preclude.hs manually or automately at startup. -- Sincerely, Forest Liu(�����S)
