I just downloaded the mysqldb module from sourceforge to have a look  
at how it decides how to compile its C extension. It looks like it's  
getting the CFLAGS and LFLAGS from mysql_config. You'll need a  
universal binary of libmysqlclient (as Chris already pointed out). At  
any rate, you'll want to try to see what CFLAGS/LFLAGS were used to  
compile libmysqlclient. You might try to run the following command in  
terminal:

$ mysql_config --cflags

Which may shed some light on the situation. You'll be looking for  
something like this in the output:

  -arch ppc -arch i386

Which tells the compiler to include these architectures in the  
resulting binary. As Chris already mentioned, you'll also need a  
universal Python--I'm assuming you've already got that... Good luck.
