tzinfo_timezone plugin - Object::TimeZone not defined

I am trying to get my rails project working on a new machine. I am using OpenSuse 10.3 and following steps were performed, 1. installed rubygems 2. installed Rails (1.x) using Suse repository - it didn't have latest version. 3. updated gem version and Rails version. 4. installed other gems such rcov 5. installed 'tzinfo_timezone' plugin

Now 'rake db:create:all' or 'script/server' gives me error as - [code=]

/home/pavgi/agenda32/vendor/plugins/tzinfo_timezone/init.rb:4:in `remove_const': constant Object::TimeZone not defined (NameError)         from /home/pavgi/agenda32/vendor/plugins/tzinfo_timezone/init.rb:4:in `send'         from /home/pavgi/agenda32/vendor/plugins/tzinfo_timezone/init.rb:4:in `evaluate_init_rb'         from /usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails/plugin.rb:103:in `evaluate_init_rb'         from /usr/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/active_support/core_ext/kernel/reporting.rb:11:in `silence_warnings'         from /usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails/plugin.rb:99:in `evaluate_init_rb'         from /usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails/plugin.rb:44:in `load'         from /usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails/plugin/loader.rb:33:in `load_plugins'         from /usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails/plugin/loader.rb:32:in `each'          ... 17 levels...         from /usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/commands/server.rb:49         from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'         from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'         from script/server:3 [/code]

Now, if I comment out the line init.rb:4 [code=] Object.send(:remove_const, :TimeZone) [/code] then above rake command and server start runs successfully. What and where could be the problem? Where do I define the constant Object::TimeZone? Any help for debugging? (The same code runs successfully on my old machine.)

Thanks, Shantanu.

I don't know the reason behind this problem. I fixed (bypassed?) it by adding if condition in the tzinfo_timezone plugin's init.rb file. require 'tzinfo_timezone' New init.rb file: # remove the existing TimeZone constant if Object.const_defined?(:TimeZone)   Object.send(:remove_const, :TimeZone) end

# Use TzinfoTimezone as the TimeZone class Object::TimeZone = TzinfoTimezone

Please reply if you know the reason behind this problem.
