Redmine installation - ruby rails 2.3.11 manual download

I am having a very hard time finding Rails 2.3.11 to download. I am trying to install this on Windows XP which Redmine 1.2.x requires this version. When I try to install the gem through the command prompt this is what I get:

C:\>gem install rails -v=2.3.11
ERROR: Could not find a valid gem 'rails' (=2.3.11) in any repository
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEOUT: A connection attempt failed because the connected party ddi not properly respond after a period of time, or established connection failed because connected host has failed to respond. - connect(2) (http://rubygems.org/latest_specs.4.8.gz)

I believe th开发者_开发问答is problem is due to my highly secured internet connection. So I would like to manually download Rails 2.3.11. But I cannot find it. It seems it should be here: http://rubyforge.org/frs/?group_id=307 but the needed version 2.3.11 is not listed!
