 As I said, this problem was unfamiliar to me. ("1" looks like a positive
 integral argument to me.) I'm not sure why it occurred, nor why when you
 tried again it would then work.

 Do not be surprised that gcc47 required apple-gcc42. We are considering
 making ''all'' ports require apple-gcc42 on Tiger, since the gcc 4.0
 included with Tiger's Xcode is so old. More importantly, the linker in
 Tiger's Xcode is very old. llvm-3.0 is a dependency of ld64, and ld64 is a
 dependency of all the gcc4''x'' ports now. I don't know why ld64 was added
 as a dependency of the gcc4''x'' ports globally instead of just for Tiger
 but presumably there is a reason.
