On that note: more good news. While I haven't round-tripped through
notarization again yet, this is a bit less dire than it first appeared. If I
prevent the import of ctypes with an `import sys; sys.modules['ctypes'] =
None`, and add a 'sed' script to my build process to prevent _setup_ctypes from
running in __boot__, then the app launches again.
Apparently my app doesn't actually need ctypes.
The problem seems to be that Twisted includes a ctypes import; modulegraph sees
this and thinks there is a hard dependency, and inserts the ctypes setup blob
into __boot__. However, this is a conditional import, and it's for Windows
support anyway.
(There also seem to be problems with cffi-using libraries, but not other shared
objects, so maybe this is a bug in libffi; however, these don't interfere with
py2app itself starting up.)
