pyzmq==27.0.1 error on AIX 7.2

Hi all, I have an AIX 7.2.0.0 setup where, using pyenv we install python 3.11.3, then we install pyzmq If I run just import zmq I get an error, I even tried setting the compiler to IBM for C, C++ and using pip install pyzmq --no-binary pyzmq --no-cache-dir, the result is the same. ``` (venv) bash-5.2$ python Python 3.11.3 (main, Nov 22 2024, 16:34:57) [GCC 10.3.0] on aix Type "help", "copyright", "credits" or "license" for more information. >>> import zmq Illegal instruction (core dumped) ``` We use AIX open source tool box, to use dnf package manager to install gcc, g++ and other dependencies needed to run pyenv, deploy virtualenv, install python3.11.3 pyzmq==25.0.0 works fine without issues, but anything after fails I have tried building libzmq from sources using C,C++ compiler on AIX and then linking it to a C,C++ sample code, but the C/C++ binaries work fine.
