I have pushed the fix in commit 915114f:
https://github.com/macports/macports-ports/commit/915114fea92aea919a64ffbddb504348cc378061

I *think* this is it since on previous attempts I "heard back" from the 
buildbots not soon afterwards but now they're quiet.

Thanks to Ken, Joshua and Ryan for being so helpful. Special kudos to 
Ken for promptly helping me after my request to this list.
