New #FreeBSD #go problem with the ports anyway: my port use go modules, but I need to run `go generate` before building.
The port systems seems to have nothing built-in, and running `go generate` with the same environment as `go build` produce an error:
$GOPATH/go.mod exists but should not
If I strip the env, it downloads the source again.
Can someone point me to the good direction for fixing this?
