 My rdiff-backup script fails on snow leopard because of this issue that
 arose with python25. When run as root, os.getgroups() causes an OSError
 exception. This did not occur on 10.5, but it occurs on 10.6 with
 '''both''' python 2.5 and 2.6.

 As I said, my main concern is getting rdiff-backup to work as root. That
 relies explicitly on python25, but I imagine the fix would be the same for
 both. Incidentally, the python 2.6.1 distributed with the OS does not
 exhibit this problem, so building rdiff-backup against that may be a
 workaround.
