Comment:

 Replying to [comment:5 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.
