The following will exclude users of Mac OS X 10.3:


platform darwin 7 {
	pre-fetch {
		return -code error "${name} requires Mac OS X 10.4 or newer"
	}
}


This assumes nobody has MacPorts installed on Mac OS X 10.2 or  
earlier anymore. MacPorts 1.7.0 doesn't install on Jaguar and earlier  
anyway.
