bundle install fails with SSL certificate verification error

When I run bundle install for my Rails 3 project on Centos 5.5 it fails with an error:

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 
read server certificate B: certificate verify failed 
An error occured while installing multi_json (1.3.2), and Bundler cannot continue.
Make sure that `gem install multi_json -v '1.3.2'` succeeds before bundling.

When I try to install the gem manually (by gem install multi_json -v '1.3.2') it works. The same problem occurs with several other gems. I use RVM (1.12.3), ruby 1.9.2, bundler 1.1.3.

How to fix it?

    Now that I've karma wh..err mined enough from this answer everyone should know that this should have been fixed.

    re: via Ownatik again bundle install fails with SSL certificate verification error

    gem update --system

    My answer is still correct and left below for reference if that ends up not working for you.

    Honestly the best temporary solution is to

    [...] use the non-ssl version of rubygems in your gemfile as a temporary workaround.

    via user Ownatik

    what they mean is at the top of the Gemfile in your rails application directory change

    source 'https://rubygems.org'


    source 'http://rubygems.org'

    note that the second version is http instead of https
