Description of problem:
A recent update included a newer version of rubygem-nokogiri which no longer satisfies the gem dependencies of rubygem-aws-sdk.

Version-Release number of selected component (if applicable):
rubygem-aws-sdk-1.3.7-1.fc16.noarch

How reproducible:
Always

Steps to Reproduce:
1. yum -y upgrade on Fedora 16
2. Run a ruby script which requires aws-sdk

  
Actual results:
$ ./devenv

Expected results:
The script runs

Additional info:
Upgrading the RPM to aws-sdk-1.4.1 solves the problem and requires minimal changes to the specfile (just download the newer gem and update version number).
