title: Why can't I check my version of GCC compiler on OS X
body: <p>I typed this in my terminal:</p>
  
  <p><code>llvm-gcc --version</code></p>
  
  <p>But what I have is this :</p>
  
  <pre><code>Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
  Target: x86_64-apple-darwin13.0.0
  Thread model: posix`
  </code></pre>
  
  <p>Am I not able to interpret this block of statements? or did I forget to enable something on my system?</p>
