pandoc "not fetchable"?

[John MacFarlane]

According to the port survey,
http://people.freebsd.org/~fenner/portsurvey/textproc.html#pandoc,
the distfile for the port I maintain (textproc/pandoc) is not
fetchable:

http://pandoc.googlecode.com/files/pandoc-0.3.tar.gz: 404 Not Found
(Last OK result NEVER [checked 12 times since Tue Feb 13 

I can't understand why. The file is there on the server, I can fetch it
from that URL using wget, and when I install the port, it fetches the
file just fine from http://pandoc.googlecode.com.  So why is portsurvey
not finding it?

I'm new at FreeBSD, so maybe there's something simple I'm missing.
Any help would be appreciated.
