title: Installing Nokogiri on OSX 10.10 Yosemite
body: <p>I recently upgrade to the 10.10 Yosemite beta, but I'm having trouble getting Nokogiri installed. I'm using RVM and Ruby 1.9.3. I've also followed the steps <a href="https://gist.github.com/vparihar01/5856524">here</a> and tried following the instructions on Nokogiri's homepage. </p>
  
  <p>I've installed libxml2 (2.9.1) and libxslt (1.1.28) via homebrew, and have tried using the command line tools from both my Xcode 5 install and Xcode 6 beta. </p>
  
  <pre><code>gem install nokogiri -v '1.5.5'
  Building native extensions.  This could take a while...

  <p>Anyone have an idea on how to fix these install errors?</p>
  
  <p><strong>EDIT 6/10/14:</strong> After trying for a couple days to get Nokogiri installed on OSX 10.10, I ended up abandoning the task and restored 10.9 on my machine. Several libraries and bundles need to be updated in order to work in the 10.10 environment.</p>
