The "Testing Values" section of the Apache Jena "SPARQL Tutorial - Filters" 
page (http://jena.apache.org/tutorials/sparql_filters.html) does not produce 
the expected results.

I made sure to pull the example files from the site to ensure the issue was not 
due to typos in transcription:

I then used the following query command:

$ sparql --data=vc-db-2.rdf --query=q-f2.rq

The Tutorial page indicates that the result should have been:

Version commands returned:

$ sparql --version

Please let me know if you have any suggestions for debugging this further.
