trouble compiling llvm-gcc4 1.9

I'm having some trouble getting llvm-gcc4 to compile. It's unable to compile darwin-crt3.c. It's mentioning "Complex expression. Absolute segment assumed." but I'm not sure if that's a real error message. Has anyone run into this before? I'm running on a G4 apple 10.4.8, kernel version 8.6.0. I googled around and found a bug with the same error message:

http://llvm.org/bugs/show_bug.cgi?id=958

but it looks like this was for the gcc3 frontend. I tried using the odcctools from macports, but it didn't work. Any ideas what's wrong?

Here's the relevant part of the error message:

I don't know. Two suggestions:

1. Make sure you a precisely following the information described in README.LLVM at the top-level of llvm-gcc source tarball.
2. If that doesn't work, please try mainline svn (along with mainline cvs). There have been many bug fixes and improvements since 1.9...

Not in detail, but that file is the first thing it's using the built llvm-gcc4 to compile,
so something is wrong with that. It looks like it might be misconfigured somehow.
That message is coming from the assembler and I suggest looking at the
assembler (.s) file, you may be able to figure it out from that.
To get that add -save-temps to the compilation line, which is this:

Thanks Chris and Dale! Turns out that I had a bad xcode. I had 2.2, but I thought I had 2.4. Thanks for your help.
