title: C compiler gcc not found while installing passenger and nginx
body: <p>I'm trying to install Passenger and Nginx on my VPS. </p>
  
  <p>I followed <a href="http://library.linode.com/frameworks/ruby-on-rails-nginx/centos-5" rel="noreferrer">these instructions</a> and replaced all links of all sources to the current version.</p>
  
  <p>But when i ran the Phusion Passenger installer for Nginx, something with gcc compiler went wrong:</p>
  
  <pre><code>Compiling and installing Nginx...
  # sh ./configure --prefix='/opt/nginx' --with-http_ssl_module --with-http_gzip_static_module --with-cc-opt='-Wno-error' --add-module='/usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.17/ext/nginx'
  checking for OS
   + Linux 2.6.32-220.el6.x86_64 x86_64
  checking for C compiler ... not found
  
  ./configure: error: C compiler gcc is not found
  </code></pre>
  
  <p>What should I do?</p>
  
  <p><em>OBS: My VPS works with CentOS 6.2 x64</em></p>
