It was merged to 2.5-dev in preparation to be included with 2.5.1. We had features that also were committed to 2.5-dev which required us to relabel 2.5.1 to 2.6.0 since a Z release is for bugfix exclusively. The later release 2.5.1 that occurred was a bugfix only release. Because of this the PR shows merged on 2.5-dev, but if you use --contains on the last commit of the RabbitMQ fix (33ba0e06d0100cccc2775abd8571ba6c706e7ee6) you'll see it's only on 2.6+.

Ok.  Looks like we're going to have to ship with 2.6 then.

When installing use pulp-server instead of pulp-server-qpid and pulp-consumer instead of pulp-consumer-qpid, etc. I believe that there is only 1 small feature that would fail inside of Pulp, but otherwise Pulp should behave normally. Feedback on ways to improve Pulp as it is used with RabbitMQ would be great.
Happy to help.  I've nothing against Qpid - it's that that I have 
massive infrastructure pointing at RabbitMQ - and don't intend to change 
that.

There are a couple of python-gofer-qpid dependencies in pulp-server and 
pulp-agent which I've removed: I'll have to look further into the 
python-qpid dependency.

But in a complete trick for beginners with the gofer-1.4.x to 
gofer-2.4.x upgrade for 2.6.0, somebody forgot to do the nice thing when 
renaming python-gofer-amqplib to python-gofer-amqp and putting in an 
Obsoletes/Provides.  This causes complete and catastrophic failure:

I'll be sure to post to the list as we get ready for a production 
release around 2.6 and Rabbit.
