Main.log from build

[jmroot (Joshua Root)]

Looks like an incompatibility with more recent versions of librsync. Updating rdiff-backup to the latest version (currently 2.0.5) should fix it.

[ryandesign (Ryan Carsten Schmidt)]

In bebd4f2388a297271dce3c581fcd68e56db9b360/macports-ports (master):

rdiff-backup: Update to 2.0.5

Closes: #64090
