+Clang/LLVM is installed in an "odd" location (/usr/lib/llvm/<ver>/bin/)
+which is added to PATH.  Since we cannot know <ver> upfront, it's wrong
+to hardcode the PATH at the time of installation else we'd break after a
+Clang update.  Since Clang is the primary compiler on Darwin, just
+extract the relevant path on each invocation.
