Go build system - build from local directory fails

[Marc]

Hey,

I'm trying to build a go program that is located locally, and figured
I'd use to go-build-system to do so. I've created the following

(use-modules (guix gexp)
             (guix packages)
             (gnu packages gcc)
             (gnu packages golang)    
             (guix build-system go)
             (guix git-download)
             (guix utils)
             (guix download)
             (guix build-system go)
             (gnu packages bash))

(define (vcs-file? file stat)
  "Return #t if file is a version-controlled file."
  (case (stat:type stat)
    ((directory)
     (member (basename file) '(".bzr" ".git" ".hg" ".svn" "CVS")))
    ((regular)
     ;; Git sub-modules have a '.git' file that is a regular text file.
     (string=? (basename file) ".git"))
    (else
     #f)))

(define %script-name "my-project")

(package
 (name %script-name)
 (version "0.1")
 (source (local-file "." %script-name
                     #:recursive? #t
                     #:select? vcs-file?))
 (build-system go-build-system)
 (home-page #f)
 (synopsis "")
 (description "")
 (license #f))

Which I attempted to invoke with ~guix build -f myfile.scm~ but I get
errors. The program builds without issue otherwise, but here I get the error:

command "go" "install" "-v" "-x" "-ldflags=-s -w" "-trimpath" "" failed with 
status 1

An initial suspicion is that I haven't set ‘#:import-path’ as expected
in the documentation. However, all examples I can find of this are
builds from a github repository rather than a local file, so I am not
sure what it needs to be set to.

Any clue what I could be missing?

Cheers,
