Could not find RubyGem columnize

Hi! Upon updating to rails 2.1 ( sudo gem update) I now get this error when running tests:

/Library/Ruby/Site/1.8/rubygems.rb:523:in `report_activate_error': Could not find RubyGem columnize (>= 0.1) (Gem::LoadError)         from /Library/Ruby/Site/1.8/rubygems.rb:131:in `activate'         from /Library/Ruby/Site/1.8/rubygems.rb:155:in `activate'         from /Library/Ruby/Site/1.8/rubygems.rb:154:in `each'         from /Library/Ruby/Site/1.8/rubygems.rb:154:in `activate'         from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'         from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/ active_support/dependencies.rb:509:in `require'         from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/ active_support/dependencies.rb:354:in `new_constants_in'         from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/ active_support/dependencies.rb:509:in `require'          ... 8 levels...         from ./test/unit/../test_helper.rb:2:in `require'         from ./test/unit/../test_helper.rb:2         from test/unit/user_test.rb:1:in `require'         from test/unit/user_test.rb:1
