 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:

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

Comment:

 hi Jörg, not sure what's causing this... obviously I don't see this on my
 local system. Can you please provide a bit more information, for example,
 what macOS version is this, what architecture, etcetera? Also, did you
 install with the default variants or build from source locally (i.e., what
 does {{{port installed | grep numpy}}} show?)
