Thanks for question and progress support. Additional details:
Because users might invoke arq via different OS, there is a property for it. That simplifies modification of the ant build.xml file.
<property name="arq" location="${env.JENA_HOME}/bat/arq.bat" description="executable invocation, bat/arq.bat or bin/arq"/>
As an assist, you can find a full record of output on my machine in the following log files. This is important enough to include in the sourceforge archive so that we can track progress or failures.

p.s. Ant is up to version 1.10.7 now, tested satisfactorily here.
