I'm not sure if you're refering to the "old BSD" or "new BSD" licenses, and I'm not sure if the entry on their list of approved licenses refers to the old or new BSD license either.

As far as I know, everyone's talking about the "new" BSD license. In 1999, U of C retroactively expanded the license terms on all of the existing software that was distributed under the old license to fit the terms of the new one, which is OSI Certified.
