 Unfortunate

 Just stay with clang-11 for now then, until 12.1.x rolls out. You're no
 worse off than you were three days ago.

 > Build fails on {{{libeling_rt.builtins_arm64_osx.a}}}''

 add:
 {{{use_parallel_build no}}}

 to the Portfile and report back please.

 You will notice every buildbot system (and every system of mine) had no
 trouble building this as it is. It takes several hours with parallel
 building enabled. With only one processor, you can guess it might take
 four times that long, or more, not sure.
