title: emacs can't find its things in its own load path
body: <p>the following is output from a terminal session demonstrating that I, hopefully actually set this up right.</p>
  
  <pre><code>~ $cat .emacs
  (require 'package)
  (custom-set-variables
   ;;lots of comments generated by computer
   '(package-archives (quote(("gnu" . "http://elpa.gnu.org/packages") 
                             ("marmalade" . "http://marmalade-repo.org/packages") 
                             ("melpa" . "http://melpa.milkbox.net/packages/") 
                             ("org" . "http://orgmode.org/elpa")))))
  
  (custom-set-faces
   ;;again lots of comments added by the computer
  )
  
  (add-to-list 'load-path "/usr/share/emacs/24.3/site-lisp/mu4e")
  ~ $ ls /usr/share/emacs/24.3/site-lisp/mu43
  #there are a lot of files here, but I am only going to show 2 right now
  mu4e.elc
  mu4e.el
  </code></pre>
  
  <p>... and yet emacs M-x mu4e returns [no match]. I have checked to load-path variable, and it <em>is</em> there. What am I doing wrong?</p>
