title: No command 'rvm' found, but there are 20 similar ones
body: <p>I followed the [Phusion Passenger guide][1] to install rvm on EC2. It states to do the following:</p>
  
  <pre><code>$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
  $ curl -sSL https://get.rvm.io | sudo bash -s stable
  $ sudo usermod -a -G rvm `whoami`
  $ if sudo grep -q secure_path /etc/sudoers; then sudo sh -c "echo export rvmsudo_secure_path=1 &gt;&gt; /etc/profile.d/rvm_secure_path.sh" &amp;&amp; echo Environment variable installed; fi
  </code></pre>
  
  <p>I log out and log back in and get the following:</p>
  
  <pre><code>$ rvm
  No command 'rvm' found, but there are 20 similar ones
  rvm: command not found
  </code></pre>
  
  <p>I installed rvm as root, which what I wanted. I added my user to the rvm group and so I should have system wide access. The rvm files are still there:</p>
  
  <pre><code>$ sudo find / -name "rvm"
  /usr/local/rvm
  /usr/local/rvm/src/rvm
  /usr/local/rvm/src/rvm/lib/rvm
  /usr/local/rvm/src/rvm/bin/rvm
  /usr/local/rvm/src/rvm/scripts/rvm
  /usr/local/rvm/lib/rvm
  /usr/local/rvm/bin/rvm
  /usr/local/rvm/rubies/ruby-1.9.3-p0/lib/ruby/gems/1.9.1/gems/rvm-1.11.3.9/lib/rvm
  /usr/local/rvm/scripts/rvm
  </code></pre>
  
  <p>Why can't my system find rvm?</p>
