title: Installing Ruby gems not working with Home Brew
body: <p>The gems I install via <code>sudo gem install ...</code> can't be executed (I get a <code>command not found</code>). 
  They seem to install into <code>/usr/local/Cellar/</code> which is Brew's install directory (also, the gems in <code>/Library/Ruby/</code> don't work either). Is there anything else I need to do to make the gems executable? I'm using ZSH on Mac OS X 10.6 with Ruby v1.8 for the one in Brew.</p>
  
  <p>EDIT: It seems to be working now. I just went out for a few hours and came back to try it again. </p>
