What's the point of freezing your Rails version/gems?

What does it mean to freeze a gem (in Rails 2.3)?

And how do you do so?

It's a rake task that unpacks the gems referenced in config/environment.rb into vendor/gems but his method was never very reliable and has been deprecated in favor of the new Bundler system using Gemfile.

The biggest issue with freezing gems was that compiled gems, or gems with system dependencies would never be frozen properly. Only pure-ruby gems could be properly archived.
