I'm trying to dynamically load a class from a specific module (called 'commands') and the code runs totally cool on my local setup running from a local Django server. This bombs out though when I deploy to Google App Engine. I've tried adding the commands module's parent module to the import as well with no avail (on either setup in that case). Here's the code:

mod = __import__('commands.%s' % command, globals(), locals(), [command])
return getattr(mod, command)

App Engine just throws an ImportError whenever it hits this.

And the clarify, it doesn't bomb out on the commands module. If I have a command like 'commands.cat' it can't find 'cat'.
