It looks like you compiled the "getfem_python.o" file (the messages are only
warning messages so it think it built successfully), which is an intermediate
file. You need to run make again, this time it should try to build the
_getfem.so python module, remove the "-arch ppc" , add " -framework Python" and
(maybe) it will work !
