bug#17508: 24.3.91; Emacs without dbus support and unclear error message.

[Nicolas Richard]

When emacs is compiled --without-dbus and one runs:

emacs -Q -l notifications --eval '(notifications-notify :title "foo" :body 
"bar")'

the error is cryptic:

Error: (void-variable dbus-message-type-method-call)

I would in fact expect (require 'dbus) to give an error when no dbus
support is available.

(This happened to me because I had not installed dbus-1-dev prior to
recompiling emacs.)
