Sure, which is why we have the archcheck portgroup, and more than that, why MacPorts 1.9 includes these checks for all ports (in a slightly different way). Basically MacPorts should no longer permit you to attempt to install something universal when its dependencies aren't universal.

I thought the problem here was that libvpx is attempting to install itself universal on Leopard systems, even though the user has not requested the +universal variant (thereby not performing any of the checks MacPorts usually performs).
