What about the MySQL library itself, i.e. libmysqlclient? Do you
have a
64-bit version of it? The standard distribution from MySQL is not
4-way, (and, for 5.1.30 at least, it's broken for 2-way:
<http://bugs.mysql.com/bug.php?id=41940>).

However, importing MySQLdb in python directly shows something
interesting:
>>> import MySQLdb

It tries to fine the .16 version, but the 64-bit mysql has the .15
version:
Hedwig:local larsrc$ locate libmysqlclient_r | grep .0.0
/usr/local/mysql-5.0.77-osx10.5-x86_64/lib/libmysqlclient_r.15.0.0.dylib
/usr/local/mysql-5.1.31-osx10.5-x86/lib/libmysqlclient_r.16.0.0.dylib
Linking /usr/local/mysql/lib/mysql and recompiling MySQLdb from fresh
sources gave an egg that looks for the .15 version, but now it is back
to the 'does not define init function'. No luck on that.
>>> import MySQLdb

I have cleared out my old eggs and checked that the egg used here is
64-bit.
Any ideas also why there is no 64-bit installation of Python for Mac?
Given the presence of fat binaries, it seems like it would be a
trivial task to have it.
The support for 4-way universal builds in python is relatively new.
There has been some discussion recently on the python-dev list about
providing "official" 4-way installers for OS X. This will probably
get
discussed more at the upcoming PyCon.
I hope so. All this grief has had me casting about for another
language to do really simple MySQL-to-JSON web services, but I have
found nothing that does it as well as Python and Publisher.
