Autocomplete step doesn't know where bundler is...

[tnypxl]

Not sure what to do here. I've been investigating this issue for a while and I can't quite understand why it's not finding the bundler gem. Below is the error I get:

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in gem_original_require': no such file to load -- bundler (LoadError) from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:inrequire'
