In your original report you stated that sip was built with just '--arch
i386'. '--platform macx-clang-32' is not supported and configure.py will
generate an error message if used, so I don't see how that configuration
could be created.

With a clean PyQt, set the QMAKESPEC environment variable to macx-clang-32
and then run configure.py. That works for me.
