Importing PyQt5* fails on Mac

[Grzegorz Bokota]

Dear Phil,
I just tested PyQt5 wheels on macos 13.2.1 and got:

In [2]: from PyQt5.QtWidgets import QApplication, QLabel
   ...:
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
Cell In[2], line 1
----> 1 from PyQt5.QtWidgets import QApplication, QLabel

ImportError:
dlopen(/Users/sobolp/micromamba/envs/napari-419/lib/python3.11/site-packages/PyQt5/
QtWidgets.abi3.so, 0x0002): Symbol not found:
__ZTVNSt3__13pmr25monotonic_buffer_resourceE
  Referenced from: <8239A761-D3BE-396C-A445-F703655273B5>
/Users/sobolp/micromamba/envs/napari-419/lib/python3.11/site-packages/PyQt5/Qt5/lib/QtWidgets.framework/Versions/5/QtWidgets
  Expected in:     <3EE92404-8FC3-374B-A598-D5C9A8CD64B5>
/usr/lib/libc++.1.dylib

The wheels are tagged as 11.0 compatible. Also, wheels on from riverbank
pypi (https://www.riverbankcomputing.com/pypi/) are working without any
problem on this machine. could you chek what may have men changed and
rebuilt the wheels?

Regards,
Grzegorz Bokota
