I'm not sure what other details I can provide that would be helpful since the repo is private but happy to provide whatever additional details I can.

$ goda graph -cluster -short "github.com/me/app:all" | dot -Tsvg -o graph.svg

This may already be fixed by #61. Can you try building goda from the master branch to see if that helps?

[egonelbre]

I added a new tag. Yeah, it seems I forgot to make one before.

[egonelbre]

Hopefully this was fixed by #64.
