[xmonad] Xmonad-contrib build failure

Hi all,
I am building XMonad-Contrib using cabal-install and I get the following
error:
XMonad/Hooks/UrgencyHook.hs:359:48:
    The section `5 `seconds`' takes one argument,
    but its type `Int' has none
    In the `duration' field of a record
    In the expression:
        DzenUrgencyHook {duration = (5 `seconds`), args = []}
    In the definition of `dzenUrgencyHook':
        dzenUrgencyHook = DzenUrgencyHook
                            {duration = (5 `seconds`), args = []}
cabal: Error: some packages failed to install:
xmonad-contrib-0.8 failed during the building phase. The exception was:
