How to install Connectors in Squeak 4.5

I would like to install the latest Connectors from the ss3 repository here http://ss3.gemstone.com/ss/Connectors.html

I'm having difficulty installing in Squeak 4.5. Using the Installer script results in MessageNotUnderstood: InstallerUrl>>project:

This is the Installer script

(Installer url: 'http://ss3.gemstone.com/ss/')
    project: 'Connectors';
    install: 'BroomMorphs-Base';
    install: 'BroomMorphs-Connectors';
    install: 'CGPrereqs';
    install: 'Connectors';
    install: 'ConnectorsBasicDistro';
    install: 'ConnectorsDemo';
    install: 'ConnectorsGraphLayout';
    install: 'ConnectorsShapes';
    install: 'ConnectorsText';
    install: 'ConnectorsTools';
    install: 'FSM'

How do I do this?

The install order is wrong, you can use:

(Installer repository: 'http://ss3.gemstone.com/ss/') 
    project: 'Connectors';
    install: 'FSM';
    install: 'BroomMorphs-Base';
    install: 'BroomMorphs-Connectors';
    install: 'CGPrereqs';
    install: 'Connectors';
    install: 'ConnectorsText';
    install: 'ConnectorsTools';
    install: 'ConnectorsShapes';
    install: 'ConnectorsBasicDistro';
    install: 'ConnectorsDemo';
    install: 'ConnectorsGraphLayout'
