i'm trying to build a golang package that i have just imported. its repo has a tag with unicode in it, namely v½.2.0, as observable at https://github.com/klauspost/pgzip/tags

(define-public the-pkg
  (package
    (name "go-github-com-klauspost-pgzip")
    (version "1.0.2-0.20170402124221-0bf5dcad4ada")
    (source
      (origin
        (method git-fetch)
        (uri (git-reference
               (url "https://github.com/klauspost/pgzip")
               (commit "0bf5dcad4ada")))
        (file-name (git-file-name name version))
        (sha256
          (base32 "0dgp2iljvhibzxia1g3lsfg4bjmfh4kf0bfrmfi7sd49hwhrvk7s"))))
    (build-system go-build-system)
    (arguments '(#:skip-build? #t #:import-path "github.com/klauspost/pgzip"))
    (home-page "https://github.com/klauspost/pgzip")
    (synopsis "pgzip")
    (description
      "Package pgzip implements reading and writing of gzip format compressed files, as
specified in @url{https://rfc-editor.org/rfc/rfc1952.html,RFC 1952}.")
    (license license:expat)))

i have attached the build log, but the essence is this:

guile: warning: failed to install locale

and i can't get rid of this^ warning. i installed glibc-locales to root and my user, reconfigured, restarted the guix-daemon.

which is probably the cause of the ultimate error:

warning: failed to delete .git/refs/tags/v??.2.0: No such file or directory
r:sha256 hash mismatch for...

the daemon starts from an empty env:

https://git.savannah.gnu.org/cgit/guix.git/tree/nix/libstore/build.cc#n1590

and then copies the env from the derivation, but it doesn't seem to contain any LANG value. i assume guile is also launched then without a LANG env. BTW, guile could be more informative in its warning, too.
