mountain lion install broken?

edit

I've been following the instructions on (http://www.ros.org/wiki/fuerte/Installation/OSX/Homebrew/Source) to install ros/fuerte on a macbook...(OSX 10.8). I get to the line:

brew install ros/fuerte/swig-wx

which generates the following error:

bash-3.2$ brew install ros/fuerte/swig-wx ==> Cloning git://github.com/wg-debs/swig-wx.git Cloning into '/Library/Caches/Homebrew/swig-wx--git'... fatal: remote error: Repository not found. Error: Failure while executing: git clone --no-checkout --depth 1 --branch upstream/1.3.29 git://github.com/wg-debs/swig-wx.git /Library/Caches/Homebrew/swig-wx--git

In the troubleshooting part of the page, it says that the git repository has been removed, and provides some code.

require 'formula'

class SwigWx < Formula url 'git://github.com/ros/swig-wx.git', {:using => :git, :tag => '1.3.29_fuerte'} homepage 'http://www.swig.org' version '1.3.29'

def install ENV.universal_binary system "./configure --prefix=#{prefix}" system "make" system "make install" end

end

Can anybody tell me what am I supposed do with this code? Or maybe this is a red herring?

Thank You!!!
