The test script has a couple of bugs, which I've now fixed.  Attached
is the patch I've pushed to expose the bug.

Note that the following squash-in is enough to cause the test to pass:

  diff --git a/tests/test-driver-is-distributed.test 
b/tests/test-driver-is-distributed.test
  index 09ea45a..4bb03d7 100755
