It looks like Ruby/Amazon is asking openssl whether it supports the
sha256 algorithm and openssl is saying no. Before you go any further
with this I found the following on the homepage for Ruby/Amazon:

"Amazon is discontinuing v3 of the AWS API as of 2008-03-31. Ruby/
Amazon will cease to work at that time.
Ruby/AWS is the successor to Ruby/Amazon and works with v4 of the AWS
API. Please use that library instead of this one."
