If your way of distribution is a tweaked version of setup, you MUST provide the tweaked sources to your customers per the GPL anyway. If you provide all sources of all binaries you're delivering to your customers, you're basically off the hook anyway. Given that space and bandwidth is not much of a burden these days, it's the easiest way to comply with the idea of open source and their licenses. The setup tool is designed for source distribution anyway, so that's no problem at all. Apart from that, Brian is right. You should really ask a lawyer who's specialized in licensing. Nobody here is qualified to give an answer standing up in court.
