30446 Update pynac to 0.7.27 to fix wrong result on symbolic exponentiation dkrenn "Before this ticket:

Clearly, both should be the same, namely the second.
This was on !SageMath 9.1 on openSUSE Leap 15.2 (64bit) (reported by a colleague to me).
I've tried to reproduce, but my !SageMath, as well as on !CoCalc crashes. The error message on my machine was
{{{
Traceback (most recent call last):
File """", line 25, in
ModuleNotFoundError: No module named 'Cython'
Error while executing Python code.

Unhandled SIGABRT: An abort() occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.

Aborted (core dumped)

However, my !SageMath seems to be fine otherwise, `make ptestlong` passes.
