先问一句：rails.vim 是不是不能用 vundler 管理？

前提：我已经安装了 rails.vim

但是，当我用 vim 打开一个 rails 工程中的文件时，都会提示说 Disabling rails.vim: autoload/rails.vim is missing 并且 Rfind Rcd 等命令都不能使用。

另外，每次我打开/etc/vimrc文件时，都会有一些错误提示

Error detected while processing /etc/vimrc:
line   15:
E117: Unknown function: vundle#rc
line   18:
E492: Not an editor command: Bundle 'gmarik/vundle'
line   21:

line   29:

这些正好是 vundler 的配置命令，大家是怎么避免这种错误的？

附 /etc/vimrc 配置文件

   set fileencodings=ucs-bom,utf-8,latin1
