Scala not working with heroku example
===

I'm following a tutorial to create a scala web app with Heroku here: https://devcenter.heroku.com/articles/scala

I've copied there example exactly, but when I run

    sbt clean compile stage

It fails to compile because of these errors:


    [error] /home/ajcrites/dev/dyl/src/main/scala/Web.scala:1: object jboss is not a member of package org
    [error] import org.jboss.netty.handler.codec.http.{HttpRequest, HttpResponse}
    [error]            ^
    [error] /home/ajcrites/dev/dyl/src/main/scala/Web.scala:2: object twitter is not a member of package com
    [error] import com.twitter.finagle.builder.ServerBuilder
    [error]            ^
    [error] /home/ajcrites/dev/dyl/src/main/scala/Web.scala:3: object twitter is not a member of package com
    [error] import com.twitter.finagle.http.{Http, Response}
    [error]            ^
    [error] /home/ajcrites/dev/dyl/src/main/scala/Web.scala:4: object twitter is not a member of package com
    [error] import com.twitter.finagle.Service
    [error]            ^
    [error] /home/ajcrites/dev/dyl/src/main/scala/Web.scala:5: object twitter is not a member of package com
    [error] import com.twitter.util.Future
    [error]            ^
    [error] 5 errors found

Basically, I think it has to do with finagle not being available or not in the packages I have or something.  However, I have no idea how to install finagle and there are neither instructions in the tutorial above nor at https://github.com/twitter/finagle

What can I do to get this to compile?
