upgrade of osx vim via homebrew..this was a huge kick in the teeth, so documenting here for future use.

homebrew vim install

$ brew tap homebrew/dupes

check to see that vim.rb is installed in: /usr/local/Library/Taps/homebrew-dupes/ 

if so:

$ brew install homebrew/dupes/vim

note: very possible that you'll encounter an error here, (i did), in which case:

$ cd ../../usr/local/Library/Taps/homebrew-dupes/ 
$ rm -r vim.rb

this nukes the bad mojo so we can start fresh
open https://gist.github.com/721952/0b2428d75052548b90e9b1d28553f4c9f56f8a0a, click 'raw' and select-all > copy

$ touch vim.rb $ vim vim.rb

paste in this vim.rb and :wq open new terminal window

$ brew install homebrew/dupes/vim

install should run smoothly now, when finished you should have a new and more stable vim enviornment
