 The summary says it all:

 {{{
 MacX:~ fw$ python3.9
 Python 3.9.1 (default, Jan 10 2021, 00:21:42)
 [GCC 4.2.1 (Apple Inc. build 5577)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import _ctypes
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ModuleNotFoundError: No module named '_ctypes'
 >>> ^D
 }}}

 This worked @3.9.0, so the workaround is to roll back if possible:

 {{{
 MacX:~ fw$ python3.9
 Python 3.9.0 (default, Nov  1 2020, 20:09:43)
 [GCC 4.2.1 (Apple Inc. build 5577)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import _ctypes
 >>> ^D
 }}}

 Observed on 10.4 i386, 10.5 ppc, 10.5 i386, and 10.5 x86_64.  Not yet
 tested on 10.4 ppc.
