cannot "make" the project

[dorroddorrod]

When running
go get -d github.com/graphite-ng/carbon-relay-ng
go get github.com/jteeuwen/go-bindata/...
cd "$GOPATH/src/github.com/graphite-ng/carbon-relay-ng"
make

i get the following error :

  cd ui/web && go-bindata -pkg web admin_http_assets/...
   find . -name '*.go' | grep -v '^\.\/vendor' | xargs gofmt -w -s
   CGO_ENABLED=0 go build -ldflags "-X main.Version=0.11.0-39-g742bbbd" ./cmd/carbon-relay-ng
   # github.com/graphite-ng/carbon-relay-ng/route
   route/grafananet.go:260:10: undefined: strings.Builder
   make: *** [build] Error 2

Please advice

you need a go version >= 1.10
