f19 and rawhide are both valid targets for rawhide builds, I have added a f19-candidate target.

fedpkg uses rawhide for master branch in git

Well, I tried dist "f19" as well as "rawhide" and was unsuccessful. Rawhide still not works. Not sure if it should:

{{{
$ fedpkg --dist rawhide -v scratch-build --srpm rubygem-openshift-origin-common-0.13.3-7.fc19.src.rpm

}}}

i personally would use koji and not fedpkg to do scratch builds of srpms

{{{
koji build --scratch f19 rubygem-openshift-origin-common-0.13.3-7.fc19.src.rpm

koji build --scratch f19-candidate rubygem-openshift-origin-common-0.13.3-7.fc19.src.rpm

koji build --scratch rawhide rubygem-openshift-origin-common-0.13.3-7.fc19.src.rpm
}}}

there is no rawhide-candidate target the command you are running is really weird.

Well, koji command is fine, but you have to remember the build targets, which fedpkg is typically doing for me.

Never mind, I'm (and fedpkg as well) fine with "--dist f19". I was just wondering. Thank you.
