The first cctools update in about 14 months looks ready to commit to me. This matches Xcode 10.2, and is the last one Apple has released so far.
As a core component of macOS and MacPorts, touching almost every system, I would appreciate anyone interested to give this a review, try to break it, etc. <https://github.com/macports/macports-ports/pull/6339 <https://github.com/macports/macports-ports/pull/6339>> Best, Ken
