 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.6.99
 Keywords:             |       Port:  py-pyqt5
-----------------------+----------------------
 The build works on some versions of macOS, but not on mine which is 10.11

 The build cannot find header file sip.h because the correct include
 directory is not specified.

 sip.h is here
 {{{
 /opt/local/Library/Frameworks/Python.framework/Versions/3.8/include/python3.8m/sip.h
 }}}

 Here is the failing command
