Hi ya.
To install GNUnet from git on GUIX I use modified (removed check phase) package definition as tests fail:
(define-public gnunet-git (package
(name "gnunet")
(version "0.16.3")
(source (local-file "/home/gnunet" #:recursive? #t))
(build-system gnu-build-system)

(synopsis "Secure, decentralized, peer-to-peer networking framework")
(description
"GNUnet is a framework for secure peer-to-peer networking. The
high-level goal is to provide a strong foundation of free software for a
global, distributed network that provides security and privacy. GNUnet in
that sense aims to replace the current internet protocol stack. Along with
an application for secure publication of files, it has grown to include all
kinds of basic applications for the foundation of a GNU internet.")
