Sure enough, that explains the difference. I was sure it couldn't 
possibly be something that simple, since git history shows that the only 
change in the setup script was the version number, but of course that 
doesn't show the command line arguments used to invoke the script. I 
must have switched at some point in the past and forgotten about it. 
(And the build machine isn't running right now, so I only have my laptop 
to test it on.)

Thank you - back to more productive work now...
