Import error with Google App Engine

[GoogleCodeExporter]

1. Use Google App Engine
2. "import passlib.hash" in one of your modules.

And you will get a result similar to the following:

Traceback (most recent call last):

Tested on Linux and GAE 1.5.2

Thanks for reporting this. It looks like there's a couple of glitches that need 
fixing before Passlib works properly under GAE. I'll update this issue when 
it's done.

Passlib 1.5.1 has now been released, which should fix this bug. All unittests 
now pass under gaeunit on both development and production GAE environments.
