Patch says it all.
Fix: Patch for databases/db2. db3 and db4 have that problem too.
(also at http://www.livejournal.com/users/pauamma/4134.html)
How-To-Repeat: more /usr/ports/database/db/pkg-descr
database/db live in ports
Note that this should have always been a 'ports' PR, since it affects
parts of the FreeBSD Ports Collection ('docs' is only for documentation
that describes the overall system), and the maintainer of db41 should
have been Cc:ed. (Since the cosmetic change is so minor, in this case
I have gone ahead and done the commit without asking first, but in the
general case that's how it should be done).
