title: Fixing "custom_require.rb:36:in `require': no such file to load" errors
body: <p>I understand that after Ruby 1.9.2, '.' is no longer in your path for security reasons. This seems to be a problem when using certain gems (ones not updated to 1.9 I imagine?), a problem that throws errors like </p>
  
  <p><code>$HOME/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in 'require': cannot load such file -- rubylog (LoadError)</code></p>
  
  <p>I've seen and fixed this problem once, by (perhaps naively) changing some requires into require_relatives: <a href="https://github.com/mathpunk/MongoDB_Koans/commit/e2f7898347d328450ec121d22f701508f389cc53" rel="nofollow">https://github.com/mathpunk/MongoDB_Koans/commit/e2f7898347d328450ec121d22f701508f389cc53</a></p>
  
  <p>Now I'd like to use rubylog, and I'm getting the custom_require error, so I tried the same trick:
  <a href="https://github.com/mathpunk/rubylog/commit/995e13dccc6a197d280d0783f3fb7fe50deabd02" rel="nofollow">https://github.com/mathpunk/rubylog/commit/995e13dccc6a197d280d0783f3fb7fe50deabd02</a></p>
  
  <p>but this time, I'm just getting the same error. What else can I try?</p>
  
  <p><strong>ETA:</strong> All this time, I've been using <code>sudo gem install blah</code> to install gems, and for some reason, for rubylog it's <code>gem install rubylog</code> that does it. (Something to do with RVM?) So now everything works. Thank you.</p>
