Description (last modified by zooko)

In a recent build for FreeStorm CentOS6-amd64: 

Searching for pyasn1>=0.0.8a

A release candidate should never be a "best match" for a dependency; that is just asking for trouble. In this case the build failed because the release candidate wasn't actually downloadable, but even if it had been, we only want to use releases.
