There is a :: missing between the function name and its type.

> ________________________putWordStat::(Word,WordCount)->IO()

The function definition is also missing an = sign:

> ________________________putWordStat(w,wc)
> ________________________do

should be

> ________________________putWordStat(w,wc)=
> ________________________do

Finally, in this whole block:

> ________printFreq wl=do sequence (map putWordStat wl)
> ________________________where
> ________________________putWordStat::(Word,WordCount)->IO()
> ________________________putWordStat(w,wc)=
> ________________________do ...
> ________________________return()
> ________________________wlLength-countWords wl;

the indentation is incorrect.  You probably meant to write something
along these lines:

> ________printFreq wl=do sequence (map putWordStat wl)
> ____________________________where
> ______________________________putWordStat::(Word,WordCount)->IO()
> ______________________________putWordStat(w,wc)=
> ________________________________do ...
> ___________________________________return()
> ________________________wlLength-countWords wl;

but even this has two faults.  First, a `where' clause can only be
attached to a whole definition, not to a single statement within a
`do'.  Second, the final statement of the outer `do' should be a
statement e.g. "return (wlLength-countWords wl)", not a simple value.
