Have a look at the FFI installer (quoted below in full). It loads three 
MCZs from a particular repository location (for good measure a progress 
bar is thrown in for free ;-) Works great, less filling.

"Simple FFI installation script"
repo := MCHttpRepository
	location:'http://source.squeakfoundation.org/FFI'
	user: ''
	password: ''.
'Installing FFI'
	displayProgressAt: Sensor cursorPoint
	from: 1 to: 6 during:[:bar|
	#(
		'FFI-Kernel-ar.7.mcz'
		'FFI-Tests-ar.2.mcz'
		'FFI-Examples-ar.1.mcz'
	) keysAndValuesDo:[:index :pkgVersion|
		bar value: index*2-1.
		reader := repo versionReaderForFileNamed: pkgVersion.
		bar value: index*2.
		version := reader version.
		version workingCopy repositoryGroup addRepository: repo.
		version load.
	].
].
