Requirement is Go >= 1.1.

I stumble upon this error on Ubuntu 13.04 and stock go package:

    $ sudo go get github.com/andrix/shubc
    # github.com/andrix/shubc/scrapinghub
    /usr/lib/go/src/pkg/github.com/andrix/shubc/scrapinghub/scrapinghub.go:306: undefined:  bufio.NewScanner

    $ go version
    go version go1.0.2

Looking further, looks like the class `NewScanner` was added in Go 1.1: http://golang.org/doc/go1.1#bufio_scanner

After upgrading to Go 1.1, I was able to install and enjoy `shubc`.
