Help wanted from Mojave users

[Joshua Root]

Could someone with a 10.14 system running an Xcode version that defaults 
to building against the 10.15 SDK please try installing the tip of the 
release-2.7 branch on top of a MacPorts 2.6.4 installation? Report the 
results in the comments here:
<https://trac.macports.org/ticket/62929>

A speculative fix has been checked in, but it has yet to be confirmed to 
fix the issue by someone who experienced it "in the wild". I'd like to 
get a new release with the fix onto rsync ASAP so nobody else 
selfupdates to a broken state, but confirmation of the fix is needed first.
