The reason for the above was probably that something was cached; got
exactly the same problem when tried in debian:11 (podman) container 
w/o libpython3-dev (*) -- and after apt-get install libpython3-dev
the above cffi.FFI().verify() worked


(*) executed the following on top of
    and then ./configure in notmuch source dir...

  export DEBIAN_FRONTEND=noninteractive
  apt-get update
  apt-get install -y -q build-essential emacs-nox gdb git man \
          dtach libxapian-dev libgmime-3.0-dev libtalloc-dev \
          python3-sphinx python3-cffi python3-pytest \
          python3-setuptools gpgsm parallel
  apt-get -y autoremove
  apt-get -y clean
  rm -rf /var/lib/apt/lists/
