Thanks, I made some guesses at how the testsuite works, but I didn't (find 
out how to) run it.

I did compare the output and try to match it to the test though. I guess the 
test will fail unless the test machines have the right package installed. Is 
there some way the test should be made conditional on that?

Thanks,

Steve.
