[Haskell-beginners] A problem with a simple csv file parser

[Andy Elvey]

Hi all -

 I'm just trying to get the simple csv file parser from "Real World 
Haskell" working.
However, I've got a problem. Here's the code  -

--  A simple csv parser 
Module parseCSV where
import Text.ParserCombinators.Parsec

csvFile = endBy line eol
line = sepBy cell (char ',')
cell = many (noneOf ",\n")
eol = char '\n'

parseCSV :: String -> Either ParseError [[String]]
parseCSV input = parse csvFile "(unknown)" input

( Btw, I'm running Ubuntu 10.04, GHC 6.12.1  ) 

When I try to run this (using "runhaskell parseCSV.hs test.csv" ) I get 
the error -
parseCSV.hs:4:16: parse error on input `where'

This has me really puzzled - as far as I can see, the first line looks 
identical to a number of similar
programs that I've found (while searching for a solution to this).  So, 
if anyone can let me know
what is causing this, that'd be great!  Many thanks in advance -
- Andy
