title: Vim + Pathogen not loading help docs
body: <p>Currently I use Pathogen to organize my vim plugins.  It seems to do this fine and without a hitch but for some reason the helptags are not generated.  I don't think my file structure is at fault (although it could be) because as far as I can tell I've set it up correctly, e.g: <code>pathogen.vim</code> is in <code>~/.vim/autoload</code> and all my plugins are in <code>~/.vim/bundle</code></p>
  
  <p>My <code>.vimrc</code> is aliased to the <code>HOME</code> directory so I can quickly find it and open it and the pathogen related part looks like this:</p>
  
  <pre><code>filetype off
  call pathogen#runtime_append_all_bundles() 
  call pathogen#helptags()
  </code></pre>
  
  <p>I feel like I've tried every iteration of this I've found on the internet as well and nothing has been successful.  The plugins seem to work just fine every time but I can never get the help docs using the helptags.  I'm using Mac OSX 10.6 if that helps.</p>
  
  <p>Any advice is appreciated.  Thanks.</p>
