Problem when packaging Avizo

[Pier-Hugues Pellerin <ph@heykimo.com>]

Hello,
I've been enjoying my time with Guix so far and I've decided to packages a
few applications that
I was using before switching. I've been trying to package avizo[0], they
seem to be using meson and ninja to build the software. So I've written the
following package, but when I've tried to build it using "guix build -L .
--debug=1 avizo" I get an exception.

Maybe I've missed something in the documentation.

Thanks for your help

Package:

(define-module (avizo)
  #:use-module (guix packages)
  #:use-module ((guix licenses) #:prefix license:)
  #:use-module (gnu packages gnome)
  #:use-module (gnu packages gtk)
  #:use-module (gnu packages glib)
  #:use-module (gnu packages pkg-config)
  #:use-module (guix git-download)
  #:use-module (guix build-system meson))

(define-public avizo
  (package
    (name "avizo")
    (version "1.2")
    (source
      (origin
        (method git-fetch)
        (uri (git-reference
               (url "https://github.com/misterdanb/avizo")
               (commit version)))
        (file-name (git-file-name name version))
        (sha256
          (base32 "02h2jbgrbl2hyq6bzwryc1r47mipgdqrdh7zi44skc25w045s6q5"))))
    (build-system meson-build-system)
