Builders and mock

[Mike McGrath]

Don't upgrade mock on the builders!   Long story short, xenbuilder2 was 
having issues earlier this week staying up.  Hoping it was a known 
problem I yum updated the box.  Mock was updated.  Some of these 
updates, however, were with the exit code.  We had many builds return a 
successful result even though the build failed.  Jesse is looking into 
this and following up with the mock people.  I've since rolled back to 
the previous version - 3.0.6-1.fc6

That is all :)
