[tahoe-dev] Build error - could not import pycryptopp

[Trivedi, Nirav]

It seems trying to build according to the quickstart instructions works but the subsequent test fails with a "Could not import 'pycryptopp' for requirement 'pycryptopp >= 0.5.14'".  Could you please help shed some light on what might be going wrong?  Here is the output of /opt/bin/python setup.py test

Hi, I wanted to know if Tahoe-Lafs currently supports using cloud service providers, such as Amazon S3 as backend storage?  I saw a slide on RAIC - Redundant Array of Inexpensive Clouds but do not seem to be able to find in the documentation any reference to how to configure clouds as storage.  Is this a feature that is not yet implemented but planned?  Thanks.
