It is my impression that you must specify --arch=i386 for sip and -- 
use-arch i386 for PyQt because the Qt installer for OS-X installs a 32- 
bit library. I don't know whether this is the cause of your error.

Even if you do give it those flags, it is my belief, based on  
extensive experiments, posts to this list, and a communication from  
Mark Summerield, that PyQt will not compile on OX 10.5 or 10.6 using  
Python 2.5 or 2.6. Error messages vary, but near the end of the make  
there are symbols missing. Here's what I get on 10.5, either on a  
MacBook Pro or Mac Pro with --arch=i386 for sip and --use-arch i386  
for PyQt:

rm -f libpythonplugin.dylib
g++ -headerpad_max_install_names -arch i386 -single_module -dynamiclib  
-o libpythonplugin.dylib pluginloader.o moc_pluginloader.o  -F/Library/

framework Carbon -framework AppKit -framework QtCore -lz -lm - 
framework ApplicationServices
