vim neocomplete issue

On my Mac, after I setup the Vim dev configuraion, usually I'd love to use http://vim.spf13.com/ to config all my plugins.

Today I got the following warnings:

"neocomplete does not work with this version of Vim.
It requires Vim 7.3.885 or later with Lua support ("+lua")."

The solution to fix that for vim on Mac:

brew uninstall vim

brew install luajit

brew install vim --with-luajit

For macvim on Mac

brew install macvim --with-cscope --with-lua --override-system-vim

on Ubuntu:

sudo apt-get install vim-gnome

vim tip
force to save system level file in vim with normal user previlledge:

:w !sudo tee %
