‘%patch-path’ is defined like this:

--8<---------------cut here---------------start------------->8---
(define %patch-path
  ;; Define it after '%package-module-path' so that '%load-path' contains user
  ;; directories, allowing patches in $GUIX_PACKAGE_PATH to be found.
  (make-parameter
   (map (lambda (directory)
          (if (string=? directory %distro-root-directory)
              (string-append directory "/gnu/packages/patches")
              directory))
        %load-path)))
--8<---------------cut here---------------end--------------->8---

So patches are looked up in the “gnu/packages/patches” sub-directory
relative to the load path entry that contains “guix.scm”.

Presumably /home/anonimo/Documentos/guix/ contains guix.scm and so
patches are expected to be in
/home/anonimo/Documentos/guix/gnu/packages/patches.

Is it the case?  Or could it be that only “4store-fix-buildsystem.patch”
is missing?
