Easily open the rubygems.org page for gem from Vim.
Use :Gem rails to open up rails on rubygems.org. If the cursor is located on a gem name you can use :Gem to open up the rubygems.org page for that gem.
Using pathogen.vim:
cd ~/.vim/bundle
git clone git://github.com/arvida/vim-open-rubygems.git
Otherwise just copy the contents of open-rubygems.vim's plugin folder to ~/.vim/plugins/.
Mac OS X - open-rubygems.vim currently relies on the open shell command.
