NumPy: Import error symbol not found in flat namespace '_ccopy$NEWLAPACK_'

[jbgoette (Jörg Götte)]

I tried to install py312-pandas, which failed. The error pointed me to a failing NumPy import and when I import NumPy from within python3.12 I get the following error messages:

Python 3.12.7 (main, Oct 5 2024, 01:39:55) [Clang 16.0.0 (clang-1600.0.26.4)] on darwin Type "help", "copyright", "credits" or "license" for more information.

py312-numoy itsefl install without errors. The same problem exists for py311-numoy and py313-numpy for me.
