I think I might have posted on this yesterday. If I understand
correctly the problem is that the calculated gfortran linking flags
get all the archs that the compiler / machine are capable of, which
will likely be a superset of those that python and the numpy C code
were built with. I had to set the FFLAGS and LDFLAGS to constrain the
archs. In my case that was:
export FFLAGS=-arch ppc -arch i386
export LDFLAGS=-arch ppc -arch i386 -Wall -undefined dynamic_lookup -bundle
but I guess you would need to review the scipy default link flags
output to get the right match for your system.
