Unable to Start IRB via Terminal
<p>I installed Ruby + Rails using the instructions provided by <a href="http://installrails.com/" rel="nofollow">http://installrails.com/</a>. I'm trying to launch IRB in the Terminal, and I get the following error output:</p>

<pre><code>FishHeads:jhu katie$ irb

<p>Can someone please get me started on the path of how to fix this?</p>
