You should change this to match the module name and file name.
Suppose, this file is named 'emacs.scm', then it should be:

  (define-module (emacs)

Or put in in a same-level sub-directory of your eh-guix-package,
as .../eh-guix-package/gnu/packages/emacs-snapshot.scm.

The manual does mention it as (17), but it's not very clear how to do
it right.
