The GPL states that you cannot redistribute "derivative works" with
more restrictions than you received.  (This is the so-called "viral
nature" of the GPL.)  The original UCB license, although in most ways
more liberal than the GPL, placed this "additional restriction" and
thus causes a conflict:

| 3. The name of any author may not be used to endorse or promote
|    products derived from this software without their specific prior
|    written permission.

About a year ago, the Regents retroactively adopted a revised BSD
license omitting the ad clause, so "new"-BSD-licensed software
(including everything that is actually *from* Berkeley) is in fact

                    *          *          *

As for PAM, there is no issue:

| ALTERNATIVELY, this product may be distributed under the terms of the
| GNU General Public License, in which case the provisions of the GNU
| GPL are required INSTEAD OF the above restrictions.  (This clause is
| necessary due to a potential conflict between the GNU GPL and the
| restrictions contained in a BSD-style copyright.)
