title: How do I get "gem install" to work on OS X Lion with Ruby 1.8.7 without seg faulting?
body: <p>I am novice rails/terminal user and just did a fresh Lion install + Xcode after that.</p>
  
  <p>Installed RVM but when I execute "gem install [any gem]" in terminal, I get this error:</p>
  
  <pre><code>/Users/[my user]/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
