I think you probably missed a step or two. Please confirm:

  1. Did you install Apache ANT and then navigate to the nutch folder and type in "ant"?
  2. Did you set the environment variables:
    • NUTCH_JAVA_HOME: The java implementation to use. Overrides JAVA_HOME.
    • NUTCH_HEAPSIZE: The maximum amount of heap to use, in MB. Default is 1000.
    • NUTCH_OPTS: Extra Java runtime options.Multiple options must be separated by white space.
    • NUTCH_LOG_DIR: Log directory (default: $NUTCH_HOME/logs)
    • NUTCH_LOGFILE: Log file (default: hadoop.log)
    • NUTCH_CONF_DIR: Path(s) to configuration files (default: $NUTCH_HOME/conf). Multiple paths must be separated by a colon ':'.
    • JAVA_HOME
    • NUTCH_JAVA_HOME
    • NUTCH_HOME

If you install using "ant", then you will get a new folder in /nutch called /nutch/runtime/local and this is from where you must actually run nutch.
