Comment (by raimue):

 We would generally prefer to get unified diffs for changes to the
 Portfile, as they are easier to review.

 As seen above, I applied this fix to the munin port. I had to strip one
 level of leading directory names, though. I also renamed it to match the
 naming of the other patches.

 Thank you for your contribution!
