Out of the blue, POD quit working on my site:

http://www.anabaptistbooks.com/services/opendir/

I'm also using it here:

http://www.woodburns-own.com/library/opendir.html

returning this error message:

POD encountered the following error while trying to run:
500 Can't connect to dmoz.org:80 (Cannot determine protocol)
Attempted retrieval URL: http://dmoz.org

servertest.pl says everything is OK.

Like I say, this problem cropped up "out of nowhere"; I hadn't been messing with anything.

When I learned of the problem, I upgraded to 1.80, but that makes no difference.

I would really appreciate some help, please.

Thanks,
Mark
