[Haskell-cafe] Regex multiple matches

How do I use Text.Regex.PCRE to get information on multiple matches? For
instance, in ghci I get this error message:
Prelude Text.Regex.PCRE> "foo" =~ "o" :: [(Int,Int)]
No instance for (RegexContext Regex [Char] [(Int, Int)])
arising from a use of `=~' at <interactive>:1:0-11
add an instance declaration for
(RegexContext Regex [Char] [(Int, Int)])
In the expression: "foo" =~ "o" :: [(Int, Int)]
In the definition of `it': it = "foo" =~ "o" :: [(Int, Int)]
"Real World Haskell"'s text suggests this should work, but the ghci
output is littered with errors.
Thanks for any help.
