Ok, so the issue is, you don't have the correct default import path, you should check it in 
go.mod if you have a doubt, it starts with:
> module oras.land/oras-go
>

So you must use that import path when you create your SPEC:

go2rpm -C -r oras.land/oras-go -f https://github.com/oras-project/oras-go

You must specify the forge so the package can be downloaded correctly.

Please note that the next version is a version 2 with a new import path:
oras.land/oras-go/v2
You should then create a new package for this version specifically.

But, the package still won't build because of Docker/Moby shenanigans:

oras.land/oras-go/pkg/auth/docker
# github.com/docker/docker/registry
/usr/share/gocode/src/github.com/docker/docker/registry/auth.go:144:51: cannot use 
challengeManager (variable of type 
"github.com/docker/distribution/registry/client/auth/challenge".Manager) as type 
"github.com/distribution/distribution/v3/registry/client/auth/challenge".Manager in argument 
to auth.NewAuthorizer:
    "github.com/docker/distribution/registry/client/auth/challenge".Manager does not implement 
"github.com/distribution/distribution/v3/registry/client/auth/challenge".Manager (wrong type 
for GetChallenges method)
    	have GetChallenges(endpoint url.URL) 
([]"github.com/docker/distribution/registry/client/auth/challenge".Challenge, error)
    	want GetChallenges(endpoint url.URL) 
([]"github.com/distribution/distribution/v3/registry/client/auth/challenge".Challenge, error)
FAIL	oras.land/oras-go/pkg/auth/docker [build failed]

Here the full list of Docker related dependencies according to go.mod:

github.com/docker/cli v20.10.17+incompatible
    github.com/docker/distribution v2.7.1+incompatible
    github.com/docker/docker v20.10.17+incompatible
    github.com/docker/go-connections v0.4.0

I haven't checked Docker in a while. I think gotmax did a ticket on it for the next meeting. 
I'll have a look.

Best regards,
