title: RVM bundle not found
body: <p>I just installed rvm and then the bundler gem.</p>
  
  <pre><code>➜  ~  ruby -v
  ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-darwin10.7.0]
  ➜  ~  gem list|grep bundler
  bundler (1.0.12)
  </code></pre>
  
  <p>But when I try to run the bundle command then I got the following error:</p>
  
  <pre><code>➜  ~  which bundle
  bundle not found
  </code></pre>
  
  <p>The interesting thing is that it works if I prepend "rvm ruby"</p>
  
  <pre><code>➜  ~  rvm ruby bundle
  </code></pre>
  
  <p>Still, I don't think like I should prepend rvm ruby before any command. Is this behavior correct?</p>
  
  <p><strong>EDIT:</strong> apparently the problem is that the default configuration is not remembered between shells.</p>
  
  <p>If I type "rvm 1.8.7 --default" then it works, but as soon as I open a new shell it doesn't.</p>
