Hello,

I'm trying to use go-importer to build terraform using Guix.  However, along the
way I did encounter https://issues.guix.gnu.org/54097, leading to following
error:

    $ guix import go -r --pin-versions github.com/hashicorp/terraform
    following redirection to `https://github.com/google/gnostic?go-get=1'...
    following redirection to `https://github.com/hashicorp/go-metrics?go-get=1'...
    following redirection to `https://pkg.go.dev/github.com/apparentlymart/go-textseg/v13'...

I am not sure how to work around that.  The description for the -r does say:

> generate package expressions for all Go modules that are not yet in Guix

Would it be possible to work around this bug by manually providing the failing
package, so that the import would just skip it?  If yes, how would I do so?  I
am not sure what the precise definition of "not yet in Guix" is.  Any other
ideas how to get this working?



Thank you and have nice day,
W.
