How do you know that it failed? Do you know for sure that the problem is
related to the line of code shown above? Is auth.el.gpg a valid Elisp
file?

BTW, the correct method for concatenating a directory and a file name is

(load-file
  (concat
    (file-name-as-directory (file-name-directory load-file-name))
    "auth.el.gpg"))
