You do not appear to have the regression testing data installed.
You may either specify a non-standard location (absolute path)
when running the test suite with the --data-dir option,
or, you may install it in any one of the following
standard locations: $test_script_root, /tmp, or /var/tmp with these
commands:

  cd <DESIRED_INSTALLATION_DIRECTORY>

  tar xzf moses-scripts-reg-test-data-$data_version.tgz
