So: does anyone have a clue how I can convince setuptools to build a PPC

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).
OK, but to be clear, libmysqlclient isn't something from somewhere else
that mysqldb uses -- it's the C extension of mysqldb itself, right?
Something built when I do "python setup.py install" in the mysqldb
source directory?
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
-I/usr/local/mysql/include -g -Os -fno-common -D_P1003_1B_VISIBLE
-DSIGNAL_WITH_VIO_CLOSE -DSIGNALS_DONT_BREAK_READ
-DIGNORE_SIGHUP_SIGQUIT -DDONT_DECLARE_CXA_PURE_VIRTUAL
Which may shed some light on the situation. You'll be looking for
something like this in the output:
-arch ppc -arch i386
Hmm, I don't see those. If this were a makefile situation, I'd have
some idea where to start poking further to find (or specify) these
flags. With setuptools, I haven't a clue -- what's the next step? Is
this something I can hack into setup.py, or what?
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...
Yes, I do seem to. And I can make an app (with py2app) that works fine
on PPC and Intel Macs, as long as it doesn't use mysql. So this appears
to be the last part of the puzzle.
Thanks,
