Background
Did a Hello World type test app on Lion. Used py2app to bundle it into
an OSX app. Works fine. Copied over to a fresh install of Snow Leopard
10.6.8 and works fine. Bundle is standalone.
Now, added MySQLdb and made a database connection on Lion - works as
expected - result returned from simple query. MySQL database is on a
third machine. Now copied bundle over to Snow Leopard machine (again a
fresh install) and received the following error:

Does anyone have any ideas of how to correct this.
On 10.7, did you build all of the installed MacPorts MySQL packages with
MACOSX_DEPLOYMENT_TARGET=10.6 and the 10.6 SDK? (I'm not sure how well
that is supported with MacPorts.) It's always dicey building something
on release n (10.7 in this case) and using it on release n-1 (10.6)
unless you use the appropriate SDK and deployment target. It is
generally safe to do the reverse, though: build on 10.6 to deploy on
10.7.
I went ahead and added the following to macports.conf in order to for
the target to 10.6
macosx_deployment_target 10.6
sdkroot /Developer/SDKs/MacOSX10.6.sdk

Looks like reverting back may be the only option for now.
Thanks for your help.
