Responding to http in Go on Dreamhost is pretty easy. The trick is to use FactCGI to serve it up.

I did this via a trivial conditional for my setup of developing on OSX, and deploying to Linux.

if runtime.GOOS == "linux" {
  fcgi.Serve(nil, nil)
} else {
  http.ListenAndServe(":2112", nil)
}

To cross-compile to Linux, you use the Go runtime flags.

GOOS=linux GOARCH=386 go build
