rails.vim ubuntu crash solution

download the latest vim (vim-7.1.293) source code (see
http://www.vim.org/download.php), and compiled it:

  cd vim7
  ./configure --with-features=huge
  make
  make install
if "You need to install a terminal library; for example ncurses." show after `./configure --with-features=huge`, type the following command:
  apt-get install libncurses5-dev
