help build a python package (odoo)

[Jovany Leandro G.C]

Hi,

i started building  package definition:
       
~~~
(define-module (odoo odoo)
  #:use-module ((guix licenses)
		#:select (lgpl3))
  #:use-module ((guix licenses) #:select (lgpl3) #:prefix license:)

  #:use-module (gnu packages)
  #:use-module (gnu packages python)
  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (guix utils)
  #:use-module (guix build-system python))

(define-public odoo
  (package
    (name "odoo")
    (version "9.0c")
    (source
     (origin
       (method url-fetch)
       (uri (string-append
"http://nightly.odoo.com/9.0/nightly/src/odoo_" version
".20160610.tar.gz")) (sha256
	(base32
	 "171gnax8syrz60iwi3k99di60x24z4f6c3s3wszb5xwgkir0ck7r"))))
    (build-system python-build-system)
    (native-inputs
     `(("python2-setuptools" ,python2-setuptools)))

    (arguments
     `(#:python ,python-2
       #:tests? #f))

    (home-page "http://www.odoo.com")
    (synopsis
     "ERP")
    (description
     "ERP")
    (license license:lgpl3))
  )

This appears to be the problem here. This means that you'll need to add 
"python2-xlwt" as an input of some kind 
(input/native-input/propagated-input) into the package definition. 
Unfortunately, xlwt has not yet been packaged for Guix, so that also 
needs to be added.

This works because the environment has access to the internet and so can 
download it, or it is otherwise available on your system via PYTHONPATH 
or otherwise. I imagine running the same command with "--container" 
would not work. All packages are built without access to the system or 
the internet.

Hope that helps. Good luck.
