 What happened
 [https://build.macports.org/builders/ports-10.7_x86_64-watcher/builds/4298
 after] the
 [https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/18195
 kernel panic] looks strange at first: the dozens of queued builds failed
 with:

 This happened because of an error I made while [ticket:60112 restoring the
 High Sierra buildbot worker]. I had installed a fresh copy of High Sierra
 and then intended to restore the High Sierra worker's Time Machine backup
 to it, but somehow I selected the Lion worker's backup instead. I didn't
 realize this until after the restoration completed and I booted up the new
 worker, which started the buildbot launchd plists, which tried to compile
 MacPorts with clang from Xcode 4.6.3, which is not compatible with High
 Sierra. Once I realized the error I shut down that VM, reinstalled High
 Sierra fresh again and restored the correct backup, but the pending Lion
 builds had already been consumed. I'll reschedule them.
