What about the the numpy binary?

http://pythonmac.org/packages/

This is usually kept up to date, though right now it's a version  
behind.  But it's universal and built for the Python universal package.

For building it yourself, normally python extensions will build  
universal by default.  But numpy may not.  Try setting ARCHFLAGS  
before building numpy

export ARCHFLAGS="-arch ppc -arch i386"

If you are still having problems, this is really a question that  
should be asked on the Mac python list.

Correct, because GDAL python *does* attempt to build universal by  
default, which fails because numpy is not.

[Marvin]  You think you have problems?  What are you supposed to do if  
you ARE a maniacally depressed robot?  No, don't try and answer, I'm
