Reddog, I just ran 2.49a, on Mac OS, and the Polygroup options are there. The dialogs look a bit different because Campbel added more options, and the Polygroup buttons are by default off, I turn them on by default, but they should be there. If it doesn't work for you I would check the console for possible error messages. Alsp be sure that you have only one version of Python installed. Multiple version will likely cause trouble.
