OS X users who prefer command-line Vim over MacVim (I'm sure we're few and far between) may become frustrated with the lack of features enabled in Apple's stock /usr/bin/vim. For me, seeing -clipboard and -ruby in my vim --version just wasn't gonna cut it.
Turning to Homebrew "proper" for a solution would only further that frustration:
brew search vim
If you meant `vim' precisely:
Apple distributes vim with OS X, you can find it in /usr/bin.
brew install https://raw.github.com/adamv/homebrew-alt/master/duplicates/vim.rb
