For the record, he did in fact follow my advice (removing the
ATLAS-specific defaults and letting setup.py autodetect the vecLib
framework), and it turns out my advice was incomplete.

One also needs to add

   extra_link_args=extra_link_args,

to the argument list of the Extension() call for the _dotblas module.

It worked fine on my machine because I had modified my Python config to
use "-undefined dynamic_lookup" instead of explicit -framework arguments
(this change is necessary for the neighborly cohabitation of different
Python versions, I believe. See the PythonMac-SIG archives for more
information).
