title: REE (Ruby Enterprise Edition) on El Capitan, installed through RVM, giving: [BUG] Segmentation fault
body: <p>I had 10.10 installed on my MacBook Pro Retina. During this time, I had REE 1.8.7-2011.12 on my machine working fine. I upgraded to 10.11 El Capitan and everything worked fine. I recently uninstalled and reinstalled RVM to clean up my Ruby Environment. It's been working great with Ruby 2.2.3, and other various versions. However, one of the projects I work on is a legacy application that requires the specific version of REE, <code>ree-1.8.7-2011.12</code>.</p>
  
  <p>It acts as if it's installed properly. However, when I went to install my first gem, <code>gem install bundler</code>, I get:</p>
  
  <p><code>/Users/myusername/.rvm/rubies/ree-1.8.7-2011.12/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
  ruby 1.8.7 (2011-12-28 MBARI 8/0x6770 on patchlevel 357) [i686-darwin15.0.0], MBARI 0x6770, Ruby Enterprise Edition 2011.12</code></p>
  
  <p>I've spent a good portion of my day trying to resolve this without having to just create a virtual machine for this, though it would probably solve my problems. Any advice on how to prevent the Segmentation fault?</p>
