I set GUIX_PACKAGE_PATH like below:

#+BEGIN_SRC shell
export GUIX_PACKAGE_PATH="/home/feng/project/eh-guix-package/"
export PYTHONPATH="$HOME/.guix-profile/lib/python3.4/site-packages"
export GUILE_LOAD_PATH="$GUILE_LOAD_PATH:$HOME/.guix-profile/share/guile/site/2.0/"
export GUILE_LOAD_COMPILED_PATH="$GUILE_LOAD_PATH:$HOME/.guix-profile/share/guile/site/2.0/"
#+END_SRC

then add file "/home/feng/project/eh-guix-package/"

#+BEGIN_SRC lisp
(define-module (gnu packages emacs-snapshot)
  #:use-module ((guix licenses) #:prefix license:)
  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (gnu packages)
  #:use-module (gnu packages emacs))

(define-public emacs-snapshot
  (package (inherit emacs)
           (name "emacs-snapshot")
           (version "20150522.9e41e0b")
           (source (origin
                     (method git-fetch)
                     (uri (git-reference
                           (url "/home/feng/project/emacs")
                           (commit "9e41e0bc6a6fdb7a01841db62d8de42d67be534a")))
                     (sha256
                      (base32
                       "1p50nrmwnx1d6an7daz8fxkj6ylxml7g23b996ba837nlfz3l8ay"))))
           (native-inputs
            `(("autoconf" ,autoconf)
              ("automake" ,automake)
              ,@(package-native-inputs emacs)))
           (arguments
            (substitute-keyword-arguments
                `(;; Build fails if we allow parallel build.
                  #:parallel-build? #f
                                    ;; Tests aren't passing for now.
                                    #:tests? #f
                                    ,@(package-arguments emacs))
              ((#:phases phases)
               `(modify-phases ,phases
                  (add-after 'unpack 'autogen
                             (lambda _
                               (zero? (system* "sh" "autogen.sh"))))))))))

#+END_SRC

but when I run command, it told me that emacs-snapshot module can't be found.
