title: Libv8 & therubyracer - Full install on every new site deployment?
body: <p>I have a Ubuntu 12.04 server and several rails 3.2.14 sites on it. Every time I do a new site deployment (via capistrano) the first install takes 20 - 30 minutes because it does a full install of libv8, even though I have already installed the libv8 gem on the machine (and see it when I do a <code>gem list</code>). </p>
  
  <p>I've tried the <a href="https://github.com/cowboyd/libv8" rel="nofollow">binary version</a> and tried changing versions of therubyracer. </p>
  
  <p>Here's therubyracer part of my Gemfile</p>
  
  <pre><code>group :assets do
    gem 'sass-rails',   '~&gt; 3.2.6'
    gem 'coffee-rails', '~&gt; 3.2.2'
        gem 'uglifier', '&gt;= 1.0.3'
    gem 'therubyracer', '~&gt; 0.12.0'
  end
  </code></pre>
  
  <p>I've turned on verbose output in Capistrano and here's where it hangs up for ~20 minutes</p>
  
  <p><code>** [out :: 198.58.99.7] Installing libv8 (3.16.14.3)</code></p>
  
  <p>Any suggestions? Really tired of new sites taking this long to deploy. </p>
