I haven't had a chance to investigate further yet, but I'll attach a patch if I come up with something.

looks like these builtins appeared in gcc 4.1 and my 10.5/ppc system is set up with gcc-4.0 as the default compiler. Xcode shipped gcc-4.2 for this system as well, which would probably work here.

(I'm running a test build right now with gcc-4.2, having added gcc-4.0 to compiler.blacklist in the portfile).

This does fix the build. I can attach a patch, but it's probably easier to just add gcc-4.0 to compiler.blacklist than to download and apply a patch :)

Fixed on Leopard in r104757 by using gcc-4.2. For Tiger we still need to fall back to apple-gcc-4.2.

r104930. It still doesn't build for me, but that'll be a separate ticket.
