 The problems start at:

 We've seen this in tons of other ports already. See query:summary=~OSSwap
 to see a few, and look at the linked tickets in those tickets. Probably a
 defect in autoconf or gnulib or something else that goes into the creation
 of configure scripts, or alternately a defect in the macOS 11/12/13 SDKs.
 Not a defect in groff or the ports that are experiencing this build
 failure. We've worked around it in other ports by switching to the
 muniversal portgroup (which comes with its own set of difficulties).
