Are you sure that you have to use the 10.4 SDK? Just use the 10.5 SDK,
but set the deployment target to 10.4 for your 32-bit architectures.
Alternatively, you could probably use different SDK's for different
architectures. Your i386 and/or ppc builds can use the 10.4 SDK, while
your x86_64 and/or ppc64 builds can use the 10.5 SDK.

You can't have one without the other.
