libmysql is the library that PySQLdb depends on -- it is provided by 
MySQL -- it is NOT built by distutils -- it is only linked to.

nope -- I'm right -- libmysqlclient is just what you'd think __ it's the 
library for mysql clients -- provide by MySQL. I just confirmed this my 
downloading the installer from MySQL, and looking in and seeing what there:

$ file libmysqlclient.16.0.0.dylib

libmysqlclient.16.0.0.dylib: Mach-O dynamically linked shared library ppc


(I've got a PPC machine)

It looks like there is a static lib there, too.

So this is what I'd do:

get the dmg installer for both PPC and Intel for 10.4 from MySQL.

copy the intallers to your hard drive, and unpack Contents/Archive.pax.gz

poke around in there, and you'll find the dynlibs.

lipo the intel and ppc ones together, and presto!


Actually, I suppose what I'd do is install the native one on your build 
machine properly, and then use lipo to add the other one to the copy 
that's on that machine.

or use a different DB...

I think so too.

I'm not in a position to do that now -- but you can buy me a beer if we 
ever cross paths!
