I have just upgraded my org to the latest from git.  Now I cannot do an
export.  I have completely commented out any customization in my .emacs for
org mode and the problem still remains.  Every time I try to export (C-c
C-e) I get:

  Debugger entered--Lisp error: (void-function org-export-dispatch)

Any ideas what is happening?  This was working with an older version of org
(from mid last year).
