Okay. What's wrong with Xcode 6's non-GUI components? I always assumed that they were the same as the corresponding ones in the CLT.

I suspect your change has had effects that you're not seeing.

The bootstrapped compiler is not functioning correctly with the detected OS X SDK. Perhaps it was not built properly. What does this output?

    % CLANG_SRC=$(port work clang-3.6)/trunk
    % $(CLANG_SRC)/Release+Debug+Asserts/bin/clang \
        -arch x86_64 -c -integrated-as \
        $(CLANG_SRC)/projects/compiler-rt/make/platform/clang_darwin_test_input.c \
        -isysroot $(xcrun --sdk macosx --show-sdk-path) -o /dev/null
    % echo $?

What "batch version"? Do you mean the /usr/bin shims? Those point to whatever `xcode-select` says to point to. You can see what's going on for yourself:

    % echo 'int main(void) {}' | /usr/bin/clang -v -x c -o /dev/null -
