I test evaluated my .emacs (Yes, it needs some cleaning up and that is
one of my projects).   Deleted my org-contacts.el and re-cloned it via
git.  I made sure the directoy for it is added to the load-path and
placed the following in my .emacs
(require 'org-contacts)
I have attatched a backtrace of the error to this message but it seems
to revolve around: 
(org-property-set-functions-alist ("BIRTHDAY"
. org-completing-read-date))
not working correctly.    This error won't let me load the .emacs file
and thus I can't use the org-contacts functionality.  Hopefully, I am
just missing something obvious and this will be an easy fix.
