title: Install RVM on Mac OSX 10.5
body: <p>Need to use SASS / Compass locally, but the Ruby on my old Mac OSX on this machine is not compatible: <code>sass requires Ruby version &gt;= 1.8.7.</code>. After research it seems like I need RVM, but haven't been able to find out how to install this on my computer so that I can upgrade my Ruby. </p>
  
  <p>Tried this, for example:</p>
  
  <pre><code>\curl -L https://get.rvm.io | bash -s stable --ruby
  </code></pre>
  
  <p>Returns this:</p>
  
  <pre><code>curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
  error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
  More details here: http://curl.haxx.se/docs/sslcerts.html
  </code></pre>
  
  <p>Can anyone give me step-by-step instructions on how to do this? Please keep in mind that I am not very skilled in the terminal, so any copy-and-paste snippets would be helpful. Thanks a lot for your help!</p>
