title: Ruby gems not available - mac, probably PATH issue
body: <h2>The Problem</h2>
  <p>I can't install ruby gems properly, here's what I get trying to install and run chef:</p>
  <pre><code>$ gem install chef &amp;&amp; chef
  Successfully installed chef-11.6.0
  Parsing documentation for chef-11.6.0
  1 gem installed
  bash: chef: command not found
  </code></pre>
  <p>My path is:</p>
  <pre><code>$ echo $PATH
  /Users/mcarey/.rvm/gems/ruby-2.0.0-p0/bin:/Users/mcarey/.rvm/gems/ruby-2.0.0-p0@global/bin:/Users/mcarey/.rvm/rubies/ruby-2.0.0-p0/bin:/Users/mcarey/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/mcarey/.rvm/gems/ruby-2.0.0-p0/gems
  </code></pre>
  <h2>Background/History</h2>
  <p>It was all working fine until I accidentally (long story short) created a tilde (~) directory and then tried to remove it with 'rm -R ~', this of course started deleting my home directory but once it hit the first protected file it asked for permission and I cancelled it.  My old ~/.bash_profile was removed but I'm not sure what else went.</p>
  <p>Any thoughts? Any extra info needed?</p>
