I used that code earlier, and was mostly happy with it but found it
somewhat slow.  (Also, it gets into an infinite loop on OSX.  You need
to add "Volumes" to the list of directories not to recurse into,
alongside "." and "..".)  Now I'm using the following piece of elisp,
which completely ignores the Rebar configuration but gets it right for
most projects I work with:

(defun mh-simple-get-deps-code-path-dirs ()
  ;; Why complicate things?
  (and (buffer-file-name)
       (let ((default-directory (file-name-directory (buffer-file-name))))
         (file-expand-wildcards "../../*/ebin"))))

(defun mh-simple-get-deps-include-dirs ()
  (list "../include"))

(setq erlang-flymake-get-code-path-dirs-function 'mh-simple-get-deps-code-path-dirs
      erlang-flymake-get-include-dirs-function 'mh-simple-get-deps-include-dirs)
