title: "No such file to load" – can't install Ruby gems after Lion migration
body: <p>I just migrated to a new Mac with OS X Lion. For some reson I can't install new Ruby gems anymore. Or rather: I can install them, but not find them.</p>
  
  <p>This is my <code>gem env</code>: </p>
  
  <pre><code>RubyGems Environment:
    - RUBYGEMS VERSION: 1.3.6
    - RUBY VERSION: 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]
    - INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8
    - RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
    - EXECUTABLE DIRECTORY: /usr/bin
    - RUBYGEMS PLATFORMS:
      - ruby
      - universal-darwin-11
    - GEM PATHS:
       - /Library/Ruby/Gems/1.8
       - /Users/Jens/.gem/ruby/1.8
       - /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
    - GEM CONFIGURATION:
       - :update_sources =&gt; true
       - :verbose =&gt; true
       - :benchmark =&gt; false
       - :backtrace =&gt; false

    - REMOTE SOURCES:

  </code></pre>
  
  <p>Running the gem crack in irb works fine:</p>
  
  <pre><code>&gt;&gt; require 'rubygems'
  =&gt; false
  &gt;&gt; require 'crack'
  =&gt; true
  </code></pre>
  
  <p>But when I try to do the same in my text editor (Textwrangler) I run into this:</p>
  
  <pre><code>custom_require.rb:31: in `gem_original_require': no such file to load -- crack (LoadError)
  </code></pre>
  
  <p>Any suggestions?</p>
