This is a type error. You have to "mapM_", not map, see the types in the documentation and try to convince yourself that you need an IO list and not a list of IO, then that you really need an IO () and not an IO list (wich would be returned by mapM). The syntax for a list of t in haskell is [t], in case you didn't notice.
