playfair can't find the source tarball or wrong checksum

[Marco Peereboom <slash_(_at_)_peereboom_(_dot_)_us>]

While testing some SMP stuff I tried to build the whole ports tree.  I  
got as far as playfair.  Attached are the results for make and make  
REFETCH=true.

# make
===>  Checking files for playfair-0.5.0
>> playfair-0.5.0.tar.gz doesn't seem to exist on this system.
cp: /cdrom/distfiles//playfair-0.5.0.tar.gz: No such file or directory
>> Attempting to fetch /usr/ports/distfiles/playfair-0.5.0.tar.gz from

Make sure the Makefile and checksum file  
(/usr/ports/converters/playfair/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]".
