Crap. I should do a repoquery rubygem-rack* first and see if there was a
package missing from BR...

I always use mock, that's why I encountered this problem in the first

That's good information thank you. I haven't yet used fedpkg as a mock
wrapper, but only when I push to official repositories. I always wanted
to ask what is everyone's workflow when it comes to packaging and this
one tip is good to know as it will be easier to package the gems from
inside my git repo :)

Yeap, I did it a couple of times before I submitted hashie, so I am
familiar with the process :)

I have set up a repo  for that purpose but I haven't used it yet.
It's good to know all these little details you wrote about, thanks again :)
