I've gotten things working, in a somewhat tedious way:

1. For sip, I ran "python configure.py -n" to generate a universal 
binary makefile, then manually edited the makefile and added 
"-mmacosx-version-min=10.4'" to CFLAGS, CXXFLAGS and LFLAGS.

2. For PyQt, I ran "python configure.py" and then manually edited every 
makefile in the directory tree to add "-mmacosx-version-min=10.4'" to 

Things appear to have built as a universal binary. Still, if someone 
could suggest how to patch the main configure.py files to avoid all this 
manual hacking, that would be much appreciated. :-)
