Wrong checksum for examples.zip?

Hi, 
then i try to install textproc/dockbook i get follows:


>> Checksum mismatch for docbook/docbkx412.zip. (sha1)
>> Checksum OK for docbook/docbook-xml-4.2.zip. (sha1)
>> Checksum OK for docbook/examples.zip. (sha1)
Make sure the Makefile and checksum file (/usr/ports/textproc/docbook/distinfo)
are up to date.  If you want to fetch a good copy of this
file from the OpenBSD main archive, type
"make REFETCH=true [other args]".
*** Error code 1

Stop in /usr/ports/textproc/docbook (line 1501 of /usr/ports/infrastructure/mk/bsd.port.mk).
*** Error code 1

Stop in /usr/ports/textproc/docbook (line 1578 of /usr/ports/infrastructure/mk/bsd.port.mk).

examples.zip seems to be ok
