wordcount.scala error

Question

I installed scalding on my mac with OSX Lion. When I run the word count.scala program to test the installation, I get the following error message:

scalac -classpath /var/folders/_j/_7d75_hj79133bcm7xrqzvz80000gn/T/maven/hadoop-core-0.20.2.jar:/var/folders/_j/_7d75_hj79133bcm7xrqzvz80000gn/T/maven/log4j-1.2.15.jar:/var/folders/_j/_7d75_hj79133bcm7xrqzvz80000gn/T/maven/commons-httpclient-3.1.jar:/var/folders/_j/_7d75_hj79133bcm7xrqzvz80000gn/T/maven/commons-cli-1.2.jar:/var/folders/_j/_7d75_hj79133bcm7xrqzvz80000gn/T/maven/zookeeper-3.3.4.jar:/Users/BessonPascal/Desktop/scalding/target/scalding-assembly-0.8.0.jar: -d /var/folders/_j/_7d75_hj79133bcm7xrqzvz80000gn/T/script-build /Users/BessonPascal/Desktop/wordCount.scala

Here are a couple other versions of WordCount in Scalding, which I've run on OSX. The build is based on Gradle (must be 1.3 or later)

https://github.com/Cascading/Impatient/tree/master/part8

The build.gradle script shows how to pull matching versions of required libraries from the different Maven repos.

So far, I've found Gradle or Maven to be more stable for this than SBT -- at least if you're trying to run in "--hdfs-local" for Hadoop Standalone and produce "fat jars" to run on a remote Hadoop cluster.
