Required Solaris Software Group Statement is Unclear

In Setting Up the Development Environment for Writing a Data Service in Sun Cluster Data Services Developer’s Guide for Solaris OS, there is a Note that the Solaris software group Developer or Entire Distribution is required. This statement applies to the development machine. But because it is positioned after a statement about testing the data service on a cluster, it might be misread as a requirement for the cluster that the data service is being run on.
