  <p>Obviously it looks like i have the wrong version of ruby installed but I know for a fact I have ruby 1.9.2 installed:</p>
  
  <pre><code>me@host:/rails/gitlabhq$ ruby -v
  ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
  </code></pre>
  
  <p>I tried manually installing the gem which worked no problem, but bundler still returns that output and refuses to move on.</p>
  
  <pre><code>me@host:/rails/gitlabhq$ sudo gem install linecache19
  Building native extensions.  This could take a while...
  Successfully installed linecache19-0.5.12
  1 gem installed
  </code></pre>
  
  <p>I'm not sure why bundler is not installing the gem/not seeing it in the system gem library.</p>
  
  <p>I dont have RVM or anything like that installed on this server, it just uses the system ruby and system gem library.</p>
