It seems like all of your repos have only version 1.0.0-4.1, where as sourceforge download has 1.0.1 and 1.1.0 betas.
Please update repos with at least 1.0.1 and if possible with newer betas as well.
we haven't updated s3cmd's own repos in a while. I'm not even sure how. Fedora, EPEL, pypi, and sourceforge are updated with 184.108.40.206.
