Whew, that is a relief, dmatter--thank you! ^_^
Since this method of packaging appears to work it does give you a way to comply with Slicer's proposed rule changes for next year.
Heh, indeed; I'd probably still be a little nervous, since it is a slightly non-standard way of using Panda, but it's reassuring and encouraging to have confirmation of it working on a relatively clean machine, so I could see myself taking a chance on it. It would call for a bit more preparation before the competition--installing something arbitrary and seeing what gets put into the resulting folder, finding another machine to try that on, and so on--but that's no great hardship since it can reasonably be done before the crunch begins.
I have no real intention of bothering with web versions. :P
