retitle guile-git@0.5.2 (irreproducibly?) fails to build and output is non-deterministic
thanks

ci.guix.gnu.org or bordeaux has a substitute.
It's not reproducible on my machine though (in multiple ways):

$ guix build /gnu/store/l23c9ivrllza863cxpvwkhparjqs3br7-guile-git-0.5.2.drv --check
> [build completed]
> guix build: fout: derivation `/gnu/store/l23c9ivrllza863cxpvwkhparjqs3br7-guile-git-0.5.2.drv' may not be deterministic: output `/gnu/store/bwh599jbkvkx5751746ldqmsnv01j9iz-guile-git-0.5.2' differs
