Comment (by drjesacco@…):

 The culprit is py-numpy.  Specifically: the method get_flags_opt(self) in
 the file

     site-packages/numpy/distfiles/fcompiler/gnu.py

 The problem is the code in this method was crafted for an intel processor.
 Below is a reworked version of that method that will work on a PPC or
 PPC64.
