Why is my structure code not working?

package app

type ConfigSet struct {
    installed bool
}

import (
    "fmt"
    "html/template"
    "net/http"
)

func init() {
    config := ConfigSet{}

    // -------------------------------------- //
    //             CONFIGURATION              //
    // -------------------------------------- //

    // Change to "true" after configuration is done!
    config.installed = false

    // -------------------------------------- //
    //           END CONFIGURATION            //
    // -------------------------------------- //

    http.HandleFunc("/", index)
    http.HandleFunc("/index.php", index)
}

func index(w http.ResponseWriter, r *http.Request) {
    if config.installed == false {
        w.Header().Set("Location", "/install/")
        return
    }
}

I can’t understand why this is not working. The error I get is:

2012/05/21 13:22:01 go-app-builder: Failed parsing input (1 error)
2012/05/21 13:22:01 /root/TravianGAE/app/app.go:7:1: expected declaration, found 'import'

I do not understand, can I announce something there?
