I think Deneche posted info on working on Windows the other day. See
http://cwiki.apache.org/MAHOUT/buildingmahout.html
My understanding is that Hadoop on Windows isn't exactly the preferred

Looks like Hadoop itself wants to execute 'chmod' locally which would
imply this requirement. Anyone got this working on Windows?
