The emacs-substitute-variables doesn't work since haskell-snippets-dir
is defined using setq, not defcustom, hence I used the
emacs-substitute-sexps.

Ok, I changed that. See the patch in the attachment.

Subject: [PATCH] gnu: emacs-haskell-snippets: Fix haskell-snippets-dir value.

The error is (abbreviated):
No such file or directory, /gnu/store/*-emacs-haskell-snippets-*/share/emacs/site-lisp/haskell-snippets-*/snippets

The value of haskell-snippets-dir was:
  /gnu/store/*-emacs-haskell-snippets-*/share/emacs/site-lisp/haskell-snippets-*/
It needs to be:
  /gnu/store/*-emacs-haskell-snippets-*/share/emacs/site-lisp/

* gnu/packages/emacs-xyz.scm (emacs-haskell-snippets): Fix
