I just rebuilt cctools on a vanilla 10.6.8 VM, and it built fine.
Your build error occurred because you're trying to force a build against the llvm-3.9 headers with the ancient gcc-4.2, and it just can't.
gcc-4.2 can build against the llvm-3.4 headers (as it is set up to do by default), but I don't know if it can build against any other headers. My guess is no, but only Jeremy might have tried others.
If you really want to build cctools against the llvm-3.9 headers on 10.6.8 (not sure why, but just sayin'), you can do that if you force a newer compiler like clang-3.9.
You would type something like this:
sudo port -v install cctools +llvm39 configure.compiler=macports-clang-3.9
Note - you would probably then be the only person on Earth with this configuration of cctools on 10.6.8. Who knows what kind of problems you might run into that nobody could figure out?
