Emacs install intstalls Emacs ctags which conflicts with the Exuberant ctags (ctags) install. For example

```
% brew install ctags
% ctags --help | head -1 <-- exuberant ctags
Exuberant Ctags 5.8, Copyright (C) 1996-2009 Darren Hiebert
% brew install emacs
% ctags --help | head -1 <-- now it's emacs ctags
Usage: ctags [options] [[regex-option ...] file-name] ...
% brew uninstall emacs
Uninstalling /usr/brew/Cellar/emacs/23.3b...
% ctags --help | head -1 <-- emacs ctags and exuberant ctags both gone
ctags: illegal option -- -
usage: ctags [-BFadtuwvx] [-f tagsfile] file ...
% brew install ctags <-- and so on and so forth
Error: ctags already installed
Try: brew upgrade ctags
```
