New description:

 I have built python38 with the +universal variant, however, when I use the
 arm64 version it fails to create a virtualenv directory and complains
 with:

 {{{
 Traceback (most recent call last):
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py",
 line 64, in <module>
     import msvcrt
 ModuleNotFoundError: No module named 'msvcrt'

 During handling of the above exception, another exception occurred:

   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/runpy.py",
 line 185, in _run_module_as_main

   File

     import _posixsubprocess
 ImportError: dynamic module does not define module export function
 (PyInit__posixsubprocess)
 }}}

 I am running macOS 12.0.1 21A559 arm64, Xcode 13.1 13A1030d.

 To reproduce:

 {{{
 # works
 ( cd $(mktemp -d) && arch -x86_64 python3.8 -m venv venv )

 # fails
 ( cd $(mktemp -d) && arch -arm64 python3.8 -m venv venv )

 # fails
 ( cd $(mktemp -d) && python3.8 -m venv venv )
 }}}

 Seems similar to the problem described in #61282
