On Home dir:

 $ git clone git@github.com:lsdr/vim.git .vim $ cd .vim $ make install

To update:

 $ cd .vim $ git pull origin master

I build MacVim from source using a fork of the Homebrew formula. I gave it a different name just to avoid collisions.

Just brew tap lsdr/stan and then brew install lsdr/stan/melee-vim.

You can also install via URL:

brew install https://raw.github.com/lsdr/homebrew-stan/master/melee-vim.rb
