Installing ActionML PIO + UR - surprise downloading dependency Scala jar

I'm following the upgrade document from http://www.actionml.com/docs/install to get ActionML installed/upgraded ( see previous posts ). When running ./make-distribution.sh I get this error:

I have a fast and reliable Internet connection here at the office. Retrying resolved the problem.
