[Haskell-beginners] type def messes up

sometimes i have copied a typedef from a tutorial or demo and get
errors. i take the typedef out and the program runs fine.
i don't think the problem lies with the person creating the typedef
because they are very experienced.
is it possible that the matter has to do with the interpreter eg hugs
vs ghci and such?
or possibly an update of the syntax over time?
for instance, i'm going through rex page's "two dozen short lessons in
haskell" from uni of oklahoma. they use hugs and the error message for
is completely different from what i get using ghci.
