The attached patch (sip-x11-gpl-3.6-extern.patch) fixes this problem.

But now I've run into another problem:

/usr/bin/libtool: internal link edit command failed

The linker is trying to resolve symbols that (I think) are provided by the 
python executable when the extension is loaded at runtime. I hacked 
siplib/Makefile to change LFLAGS to:

LFLAGS = -framework CoreServices -bundle -bundle_loader /sw/bin/python2.2

This makes it compile and link with some hopefully harmless warnings, but I 
don't know if it works since I don't use sip/PyQt on Mac OS X.

I used Fink's python2.2, but it may work with Mac OS X's bundled Python.

Ciao,
Gordon
