Comment(by macsforever2000@…):

 Note, please don't edit the $Id: line. Can you run an update and remake
 your patch? The patch does not apply for me on the latest version. I
 noticed that ryandesign had updated the portfile after my commit, so your
 patch might not be against the latest portfile revision.

 {{{
