Comment (by k6wx):

 Thanks for looking at this.

 Here's the version.

 bash-3.2# echo "Xcode $(xcodebuild -version | awk -v ORS=' ' '{print
 $NF}')"
 Xcode 12.2 12B45b

 So, a slightly older Xcode than you.  I have Xquartz installed.  Xquartz
 says it's up-to-date at version 2.7.11.

 Did you figure out from the logs what precisely failed?  The only visible
 errors I found were these.  The configure script is such a tangled mess
 that I don't know if that's normal or not.
