Scala/SBT - What to add In Project File

I am trying to add a dependency to a scala project, and I can't seem to figure out what I need to add to fetch the jar. The code that does not fetch the jar looks like this:

import sbt._
import sbt.CompileOrder._
import de.element34.sbteclipsify._

class ProjectName(info: ProjectInfo) extends DefaultWebProject(info)
    with AkkaProject with IdeaProject with Eclipsify with Exec {

     /// STUFF HERE
     val pircbot = "pircbot" % "pircbot" % "1.4.2" 
     val pircSnapshots = "pircbot" at  "http://repo1.maven.org"
     // STUFF HERE
}

I've tried numerous different snapshots, and ways to import the jar, but whenever I go into sbt>console I see this:

> update
[info] 
[info] == update ==
[info] :: retrieving :: Where.com#scalairc_2.8.1 [sync]

scala> import org.jibble._
<console>:5: error: value jibble is not a member of package org
   import org.jibble._
              ^

Any pointers on how to get this jar into my project would be appreciated.
