body: <p>Following this tutorial [<a href="http://blog.bobbyallen.me/2014/01/11/setup-your-own-private-github-server-using-gitlab-and-ubuntu-server-12-04-lts/" rel="noreferrer">link</a>] to install gitlab on a dedicated server. I need to :</p>
  
  <pre><code>sudo -u git -H bundle install --deployment --without development test postgres aws
  </code></pre>
  
  <p>But an error occurred while installing rugged :</p>
  
  <pre><code>Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
  
      /usr/local/bin/ruby extconf.rb
  checking for cmake... no
  ERROR: CMake is required to build Rugged.
  *** extconf.rb failed ***
  Could not create Makefile due to some reason, probably lack of necessary
  libraries and/or headers.  Check the mkmf.log file for more details.  You may
  need configuration options.
  
  Provided configuration options:
      --with-opt-dir
      --without-opt-dir
      --with-opt-include
      --without-opt-include=${opt-dir}/include
      --with-opt-lib
      --without-opt-lib=${opt-dir}/lib
      --with-make-prog
      --without-make-prog
      --srcdir=.
      --curdir
      --ruby=/usr/local/bin/ruby
  
  
      Gem files will remain installed in /home/git/gitlab/vendor/bundle/ruby/2.0.0/gems/rugged-0.21.2 for inspection.
      Results logged to /home/git/gitlab/vendor/bundle/ruby/2.0.0/gems/rugged-0.21.2/ext/rugged/gem_make.out
      An error occurred while installing rugged (0.21.2), and Bundler cannot continue.
      Make sure that `gem install rugged -v '0.21.2'` succeeds before bundling.
  </code></pre>
  
  <p>So I installed rugged -> I installed CMake &amp; config-pkg :</p>
  
  <pre><code>/home/git/gitlab$ sudo gem install rugged
  Building native extensions.  This could take a while...
  Successfully installed rugged-0.21.2
  Parsing documentation for rugged-0.21.2
  unable to convert "\xC0" from ASCII-8BIT to UTF-8 for lib/rugged/rugged.so, skipping

  </code></pre>
  
  <p>But it doesnt change anything : </p>
  
  <pre><code>Errno::EACCES: Permission denied - /home/git/gitlab/vendor/bundle/ruby/2.0.0/gems/rugged-0.21.2/LICENSE
