Elm Tasks Compile Error

Tasks.el

Sorry if this is a dup. I thought I had posted this last night.

I have a new build of GHC 7.8.4 and Elm 0.15 on Mac OS X, and I'm getting an error trying to compile the Tasks tutorial code (from the blog post, http://elm-lang.org/learn/Tasks.elm).

I installed Elm via the install script (runhaskell BuildFromSource.hs 0.15).

The error I'm getting when trying to compile is:
````elm
$ elm make hello.elm

Error in package evancz/task-tutorial 1.0.0 in module TaskTutorial:

Error in definition getCurrentTime:
Could not find type 'Time'.

This error is probably due to bad version bounds. You should definitely
inform the maintainer of evancz/task-tutorial to get this fixed.

In the meantime, you can attempt to get rid of the problematic dependency by
modifying elm-stuff/exact-dependencies.json, though that is not a long term
solution.
````

The code I'm trying to compile is:
````elm
import Time exposing (second)
import TaskTutorial exposing (getCurrentTime, print)

-- A signal that updates to the current time every second
clock : Signal Time
clock =
    Time.every second

-- Turn the clock into a signal of tasks
printTasks : Signal (Task x ())
printTasks =
    Signal.map print clock

-- Actually perform all those tasks
port runner : Signal (Task x ())
port runner =
    printTasks
````

I have already run the elm-package install command from the tutorial:
elm-package install evancz/task-tutorial

Is there something else I might be missing?

Thank you!
