Hello Jone,

It was hard to get started for me, too.  But after several package
recipes with a help of Guix community in the mailing list it's easy.

First of all in ‘(use-modules …)’ you could only specify Guile modules.

After we fix parentheses, then there will an error about no existing
‘(guix build)’ Guile module.  So let's remove it.

Here is a correct version, but it requires to add more modules to
‘(use-modules …)’ because of ‘native-inputs’ and ‘inputs’ in:
--8<---------------cut here---------------start------------->8---
(define-public xfce4-cpugraph-plugin
  (package
    (native-inputs …)
    (inputs …)))
--8<---------------cut here---------------end--------------->8---
