running instruction 9 with -llvm34 +llvm39 allows the build to proceed

Did you skip step 7, which was:

  1. Rebuild cctools and ld64 to use the newer version of llvm (currently llvm-3.9): 
    sudo port -v -n upgrade --force --enforce-variants cctools -llvm34 +llvm39
sudo port -v -n upgrade --force --enforce-variants ld64 -llvm34 +llvm39

Per email, everything looked good on second attempt, but there was an issue with step #12 not deactivating ld64_127. I've added that deactivation to the instructions.
