	I would think that if the site/user wants to install a
particular module at a particular rev (for some sort of custom stuff),
they'd want site_perl to be searched before the MP installed modules
(in vendor_perl) and the base perl modules.
	I agree they could break stuff, to me that's a feature of
having the flexibilty, not a bug, primarily because I don't expect
people who don't know what they're doing to be installing modules
into site_perl (even though I know perfectly well somebody will do
so, and then be stuck 'cause they don't really know what they're doing).

	If anyone else has ideas about the ordering, please let us know
shortly as I'd like to resolve this issue this week.
