title: How to install Clang from the binary distribution?
body: <p>Clang has a <a href="http://llvm.org/releases/download.html" rel="noreferrer">binary distro</a>, of sorts, but there isn't any <code>README</code> file or anything to tell you what's in the tarball or what to do with it.</p>
  
  <p>It appears that I need to separately download and install <code>libc++</code>. I may need to copy only the <code>clang</code> binary and maybe a few others, but not all the <code>llvm-*</code> stuff. This is just judging by the lack of any C++ headers in the binary distro (although some environment-specific headers are included), and the lack of <code>llvm-as</code> and such on my existing LLVM 3.2 installation from Xcode.</p>
  
  <p>I just want to run the compiler, not develop with <code>libclang</code> or assemble LLVM assembly files. Is there an instruction page somewhere?</p>
