#64234: python39 @3.9.9+universal: Under arch arch -x86_64, ModuleNotFoundError: No
module named 'msvcrt'

Component:  ports      |    Version:  2.7.1
 Keywords:  monterey   |       Port:  python39
-----------------------+----------------------
 I have built python39 with +universal variant, however, when I use the
 x86_64 version, and import subprocess, similar to the follow up comment in
 Ticket [ticket:63782], it fails with an identical error. Since this was a
 different python port, I thought it best to create a new ticket - my
 apologies if I should have just added onto [ticket:63782].

 I am running macOS 12.0.1 (21A559), Xcode 13.2 13C90.

 In addition, since this seemed closely related (I'm more than happy to
 create another ticket), I have also built python310 @3.10.1+universal,
 however, interestingly enough, when I use the arm64 version (vs x86_64
 above), and import subprocess, it fails with an identical error.
