Instead of noise I think this is valuable information...

... if we had "troubleshooting" (or just put to emacstips.mdwn) page
we could add something along the line:

   emacs -Q -L /path/to/notmuch/elisp/dir --eval "(require 'notmuch)"

(with some explanation) there (e.g. M-x notmuch-hello & M-x notmuch-mua-mail)

(emacs manpage says -L 'add's this dir to load-path -- I verified
it "prepends"! it to load-path (like add-to-list does by default))
