What other imports must I add to get this to run. I can't seem to get it

The problem is deeper than imports.
import Text.Parsec.Prim(parse)
import Text.Parsec.Token(makeTokenParser,
GenTokenParser(TokenParser, commaSep, integer))
import Text.Parsec.Language(emptyDef)
main = case (parse numbers "" "11, 2, 43") of
Left err -> print err
Right xs -> print (sum xs)
numbers = c i where
TokenParser{commaSep=c, integer=i} = makeTokenParser emptyDef
