I printed my CLASSPATH in the bin/nutch script before it calls  
anything, and all the jars and jobs are local to the nightly  
directory which I downloaded today except for /usr/local/java/lib/ 
tools.jar. All are dated 2007-01-17 19:42.

hadoop-0.10.1-core is in there.

And the data is brand new (I delete the crawl dir before doing my  
test run.)
