title: I cannot get rvm to read my project specific .rvmrc
body: <p>I come in peace (re: rbenv) but I am super frustrated with rvm &amp; .rvmrc.  I keep on running into issues where I cd into my project folder only to find that my ruby &amp; gemset environment has not been set correctly.  So can someone once and for all tell me how to create a proper .rvmrc for my project.</p>
  
  <p>I have tried both ways that I know of:</p>
  
  <ol>
  <li>creating a .rvmrc and putting 'rvm use 1.9.2@GEMSET' in there (this works sometimes and sometimes not)</li>
  <li>using the rvm --create --rvmrc 1.9.2@GEMSET command line tool which creates a more ellaborate .rvmrc but cd'ing into my project folder is still not giving me the desired result.</li>
  </ol>
  
  <p>This problem is erratic.  I will say that I am working on two different machines and syncing my project folder via Dropbox.  So could this be a problem where rvm cannot verify the folder and therefore ignores the .rvmrc?</p>
  
  <p>Any help will be greatly appreciated.</p>
