Comment (by reneeotten):

 sure, you might be able to install {{{py39-numpy}}} (as a side note:
 installing a stub-port like {{{py-numpy}}} isn't very useful). The ticket
 I mentioned, and the issue you're having here, is that ports that require
 numpy fail to install because there is an issue when trying to import
 stuff from {{{py-numpy}}}.

 If I were to guess the command {{{python3.9 -c "from numpy.core import
 multiarray"}}} will give you the same/similar error as you see above. So
 yes, it appears that you can install numpy but it didn't do so correctly.
