 Problem:
 IB 3.0+ stops processing ruby files properly since it fails to parse them.
 As a consequence, the autoupdating of ib_outlet, and ib_action fails even
 if you first save your ruby files in Xcode.

 Solution:
 Apparently, there's a version mismatch for some reason (e.g., between 1.8
 OSX ruby and 1.9 macruby).
 I believe the fix is to modify custom_require.rb like this:

 old:      Gem.activate(spec.name, false, "= #{spec.version}")    #  breaks
 rb_nibtool.rb  (2008-07-07)
 new:      Gem.activate(spec.name, "= #{spec.version}")

 i.e., remove the "false, ", since Gem.activate no longer accepts a Boolean
 as an argument.  (Assuming that's the newer behavior.)  You should be able
 to find custom_require.rb here:

 '''/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb'''

 To test from IB, run IB's File->Read Class Files... on valid ruby file
 with ib_outlet(s) and ib_action(s) and make sure they populate the
 appropriate IB inspectors with outlets and actions.
 To test manually, run the following command on a valid ruby file with
 ib_outlet(s) and ib_action(s), and you should get some appropriate XML,
 e.g., on MyController.rb:

     '''/usr/bin/ruby
 /System/Library/Frameworks/RubyCocoa.framework/Versions/A/Tools/rb_nibtool.rb
 -p -s -f - < MyController.rb'''

 And voila, your Xcode ruby can now populate your IB inspectors again.
