This is because ConfigurationOfFuel-MaxLeske.178 still points to old repository
http://ss3.gemstone.com/ss/Fuel.html which has been drained...
ConfigurationOfFuel-MartinDias.209 should be a better starting point.
In latest Squeak trunk there is another problem: lack of squeak4.5.x support both in ConfigurationOfFuel and MetacelloSqueakPlatform>>defaultPlatformAttributes.
