Hello
Looking for some clues as to deciphering the following error:
ImportError:
dlopen(/Users/jph/Public/hello.app/Contents/Resources/lib/python2.7/lib-dynload/_mysql.so,

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.
