Attached is a proposed patch to fix the compilation issue, designed by comparing the 10.4 and 10.5 SDKs. It relies on an implementation detail, but I think it's safe to say that the PowerPC headers are frozen at this point. I have built it on 10.4. I'll try to find some volunteers on the MacPorts side to test on 10.5.
