As you can see, the default build is broken, and even when I manually use master from go-fuse, the build is still broken.

I think the easy fix would be to use a go.mod, so that all users (under modules, which is a default in the upcoming 1.13) see the same versions of all dependencies.

thanks, should be fixed now.

Why not add a go.mod? Until you do that, there likely will be many more breakages in the future, because builds aren't reproducible.
