By default, the -v or --version flag is written.

$ gem install fog -v 1.8
$ $ gem install fog --version 1.8

Additionally, you can make comparisons such as >= or ~>.

$ gem install rails -v '~> 0.14.0'

To install the latest gem

$ gem install rails:0.14.4 rubyzip:'< 1'
…
Successfully installed rails-0.14.4
Successfully installed rubyzip-0.9.9
