 MacPorts is clearly trying to build the x86_64-only version, which it
 should not do on an arm64 Mac.

 I assume that you have not edited macports.conf to set build_arch to
 x86_64. If you have done that, comment it out or set it back to arm64.

 If that's not it, are you using a third-party x86_64 terminal program,
 such as iTerm2? Try using Apple's Terminal instead.

 Or are you using a nonstandard shell that was compiled x86_64? If so, use
 Apple's ksh which is compiled arm64.

 line tools ? At present I have v 12 stable. Trying v12.3 beta now just in
 case.

 You must use Xcode 12.2 or later (or the corresponding version of the
 command line tools) on Big Sur.
