What’s the main difference between:
rake gems:install
rake gems:unpack
I had a problem with it telling me I was missing these gems. I did the rake gems:install. Then I thought I had installed the gems. But it said again , I was missing gems. After I did rake gems:unpack. It fixed the problem. Why is that?

rake gems:install does what you would expect. It calls out to rubygems.org and downloads the gems specified in the Gemfile/environment.rb.
rake gems:unpack unzips the contents of the gems specified in the Gemfile/environment.rb into your vendor/gems folder.
I believe you are just not specifying your gems and just trying to use them without adding them to the project via Gemfile(Rails 3)/environment.rb(Rails 2.X). Anything in vendor/gems is loaded automatically which I think would explain what you are seeing.
You should be putting

Rails3 has a file called Gemfile where you do:
