Comment (by ryankanno):

 Replying to [comment:13 jmroot]:
 > Thanks. Note that the ModuleNotFoundError is not relevant; `msvcrt` only
 exists on Windows, so the `subprocess` module catches that error and
 imports `_posixsubprocess` instead, which is where the actual failure
 happens.

 Gotcha - makes sense. As a note, these results above are the opposite of
 what I saw in my original ticket [#64234]. To verify the original ticket
 and for my own sanity, I ran the following:

 ||= Installation command =||= Output of `port -vq installed python39` =||=
 Arch =||= Command =||= Result =||
 || `$ port install python39 +universal` || python39
 @3.9.9_0+lto+optimizations+universal (active)

 date='2021-12-18T09:38:51+0900' || x86_64 || `arch -x86_64
 /opt/local/bin/python3.9 -c 'import subprocess;'` || ImportError: dynamic
 module does not define module export function (PyInit__posixsubprocess) ||
 || `$ port install python39 +universal` ||   python39
 @3.9.9_0+lto+optimizations+universal (active)
 requested_variants='+universal' platform='darwin 21' archs='arm64 x86_64'
 date='2021-12-18T09:38:51+0900' || arm64  || `arch -arm64
 /opt/local/bin/python3.9 -c 'import subprocess;'` || success ||

 For the sys.path, here is the path(s) from the python above:

 `arch -x86_64 /opt/local/bin/python3.9 -c 'import sys; print(sys.path)'`

 {{{#!bash

 `arch -arm64 /opt/local/bin/python3.9 -c 'import sys; print(sys.path)'`
