install sequence (rough)

this is based partly on http://blog.modp.com/2007/09/ruby-mode-for-emacs.html

first, download the ruby mode goodness:

cd ~/.emacs.d
mkdir site-lisp  # if not already there.  not sure if this is the conventional place to put elisp on mac osx...
svn co http://svn.ruby-lang.org/repos/ruby/trunk/misc ruby
cd ruby
emacs -batch -f batch-byte-compile *.el # do not forget the -f

then just use the .emacs below
