To be clear, what we have in source here is:

--8<---------------cut here---------------start------------->8---
(define-public ruby-nokogiri
  (package
    ;; …
    (arguments
     (list
      #:tests? #f
      #:gem-flags #~(list "--" "--use-system-libraries"
                          (string-append "--with-xml2-include="
                                         #$(this-package-input "libxml2")
                                         "/include/libxml2" ))))
    ;; …
    (license license:expat)))
--8<---------------cut here---------------end--------------->8---

… and it’s the #$(this-package-input "libxml2") bit that causes that
discrepancy.
