title: Does the installation of Jekyll need GCC on OSX?
body: <p><a href="https://jekyllrb.com/docs/installation/" rel="noreferrer">Jekyll Installation</a> says:</p>
  
  <blockquote>
    <p>GCC and Make (in case your system doesn’t have them installed, which you can check by running gcc -v and make -v in your system’s command line interface)</p>
  </blockquote>
  
  <p>I am using macOS Sierra. And I have installed Command Line Tools (CLT) for Xcode. And <code>gcc -v</code> produces:</p>
  
  <pre><code>Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
  Apple LLVM version 8.1.0 (clang-802.0.42)
  Target: x86_64-apple-darwin16.7.0
  Thread model: posix
  InstalledDir: /Library/Developer/CommandLineTools/usr/bin 
  </code></pre>
  
  <p>It means that I have clang installed. Do I still need to install GCC?</p>
