scalacl fails on Math.sin

scalacl does not like full class names like Math.sin. (works when Math._ is imported). Error message is misleading...
scalac version is 2.9.1.final. scalac version is 0.2.final

import scalacl._
import scala.math._

object TestSin {
def main(args: Array[String]): Unit = {
implicit val context = Context.best // prefer CPUs ? use Context.best(CPU)
val rng = (1 until args.first.toInt).map(x=>x.toDouble).cl // transform the Range into a CLIntRange

val sumsin = rng.map(x=>Math.sin(x)).foldLeft(0.0)((a,b)=>a+b*b)
println("sum sin2(x)="+sumsin)

}
}

./scalac TestSin.scala
