Can't build by adding github.com/soypat/sdf

[tjboldt]

While cloning this entire repo and building everything including examples works, starting with a new project and trying to reference soypat/sdf does not. It gives build errors. Following similar steps with sdfx do work but not in sdf. To reproduce:

1. mkdir myexample
2. cd myexample
3. go mod init github.com/me/myexample
4. Create a file with the contents of one of the example go files from soypat/sdf/examples
5. go mod tidy
6. go build

The following output comes from the build:
