scalac unable to load scalacl plugin #11

I am trying to run ScalaCL along with scala2.9.3. I put the scalacl-compiler-plugin-0.3-SNAPSHOT.jar in the $SCALA_HOME/misc/scala-devel/plugins/ folder and try to run the following Test.scala

~/repos/scala-2.9.3/test$ cat Test.scala
import scalacl._
import scala.math._

object Test {
def main(args: Array[String]): Unit = {
val a = (100 until 100000).toArray
val sum = a.map(_ * 2).zipWithIndex.map(p => p._1 / (p._2 + 1)).sum
println("sum = " + sum)
}
}

~/repos/scala-2.9.3/test$ scalac Test.scala

BTW, my java version is: openjdk version "1.8.0_20-internal-fastdebug", do I need an older version of java that matches with the scala 2.9.3?

Bests,
