py-pyilmbase @2.3.0_3: fatal error: 'numpy/arrayobject.h' file not found

​Build fails on macOS 10.7, at least for py38-pyilmbase:

Unlike builds on at least 10.9 and later, the compile command on 10.7 appears to be missing -I/opt/local/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/numpy/core/include:

I wonder if the issue is actually in the pyXX-numpy port.
