This patch no longer applies as WWW fields have moved from pkg-descr to the Makefile. I have submitted a pull request for this at https://github.com/freebsd/freebsd-ports/pull/181 - hopefully a committer will merge it soon.
My patch has been merged in https://cgit.freebsd.org/ports/commit/?id=3c06a2ea847ed22e1f41721f9b161e90506ad225 and so this ticket can now be closed.
