title: Installing ruby 1.9.3 on Mac OSX 10.8.2
body: <p>I am trying to install Ruby on my new Mac, but I'm having some issues, and was wondering if anyone can help?</p>
  
  <p>The main error is:</p>
  
  <pre><code>Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc.
  Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are
  supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was
  /usr/bin/gcc-4.2.
  </code></pre>
  
  <p>I tried to solve the error using the advice in this post "<a href="https://stackoverflow.com/questions/12578220/cannot-install-ruby-1-9-2-in-mac-osx-10-8-1-due-to-symlink-error">Cannot install ruby-1.9.2 in Mac OSX 10.8.1 due to symlink error</a>", but even after installing gcc via homebrew, I still get the aforementioned error.</p>
  
  <p>When I type <code>gcc - v</code>, I get the following message:</p>
  
  <pre><code>Using built-in specs.

  <p>Lastly, I checked my /usr/bin folder, and I see a gcc-4.2 unix executable file that is about 104KB. Is this what I should have?</p>
