Could not determine kind of name for C.CBytes in module gobolt

I am feverishly trying to set up Seabolt and failing. have given up on trying to get it to work on my Mac and have moved onto an ubuntu box now - everything runs well until I run:
go get github.com/neo4j/neo4j-go-driver/neo4j

I get this error: "could not determine kind of name for C.CBytes"

Can anyone help me??
