I don't know what are you calling an URL, builders are expected to use
the current updated repository, the difference is that they are using
a private mirror from within the infrastructure . If you want to have
the exact same version for each packagge, you need to look at the
root.log
http://buildsys.rpmfusion.org/logs/fedora-15-rpmfusion_free/10346-dosemu-1.4.0-12.2058svn.fc15/i686/root.log

But please verify that your build has the redhat-rpm-config that
contains the current fedora compilation FLAGS for each release.
I guess that the first package to verify (which indeed has an version
in updates-testing).
