Eat it. Add just a touch of mustard and you should be all set! :)

Nothing to the best of my knowledge, I don't like RPMs because they aren't fight but when a user on his random system builds one, it's all done under his username etc. When that username doesn't exist on your system it just uses root to install the package and it might ask for the password. No sweat, now you can go back to your sewing :)

mockbuild does not exist, using root
 

see http://linuxhostingsupport.net/blog/...ist-using-root

it says install the "mock" package and create the ‘mockbuild’ user
