Hello Ludovic, it seems strange to me that the Yggdrasil 0.4.7 derivation that bordeaux.guix.gnu.org tried to build has "go-github-com-arceliar-ironwood" version "0.0.0-20210912013146"[1] in the inputs. I've updated the "ironwood" package along with the Yggdrasil itself and sent the both patches. I have "go-github-com-arceliar-ironwood" version "0.0.0-20221115123222-ec61cea2f439" in my Guix version and everything builds fine on x86-64.
