I have in my own personal .emacs file the following which mitigates
the problem but requires manual configuration for every package you
work with. And at my Emacs at the workplace, I have not yet adapted
.emacs, so I was annoyed again. All the info for an automatic
solution is actually in-place in the compiled Lisp files. Even when
some installation procedure copies _only_ the compiled files.
`((,(expand-file-name ".." data-directory)
"File prefixes to transform `find-function-source-path'."
:type '(repeat (list string (repeat string))))
(defadvice find-library-name (around find-function-transform activate)
(let ((find-function-source-path (or find-function-source-path load-path)))
(let (lst case-fold-search lst2 len elt2)
(dolist (elt find-function-source-path (nreverse lst))
(setq lst2 find-function-transform-list)
(setq elt2 (pop lst2)
len (length (car elt2)))
(when (or (string= elt (car elt2))
(and (< len (length elt))
(string= (substring elt 0 (1+ len))
(concat (car elt2) "/"))))
(while (setq elt2 (cdr elt2))
(push (concat (car elt2) (substring elt len)) lst))
(throw 'found t)))
(push elt lst)))))
