"Modified BSD License" describes it pretty well. The "Modified BSD License" is a specific license, not just a generic phrase meaning "a BSD license modified in some kind of way".
See the links at http://www.gnu.org/licenses/license-list.html#ModifiedBSD vs. http://www.gnu.org/licenses/license-list.html#FreeBSD There is no practical difference for our purposes. FreeBSD is GPL-compatible too. Perhaps it should be added to our license dropdown in savannah. Best, Karl
