rimage doesn't install on Mac OS X 10.4

Simon,

Scott, can you, please, check that you have Xcode 2.4 or 
higher? (2.5 is available) Cheers, S

I am running Xcode 2.1 (I've never paid attention to this before) and
Mac OS 10.4.11.  My machine is up to date according to Software Update,
and all of the references I can find for Xcode talk about Leopard.  Do I
need a more recent version of Xcode for Tiger, and if so, how can I get
it?  Or is my only option to get Leopard?
