Debian doesn't have to try to match the unattainable goal of 100% binary compatibility with an upstream source. I've seen a small part of this first-hand, and deducing the build order to gain binary compatibility is the one thing that can single-thread the build process quicker than anything else. RHEL doesn't even have the same need; an RHEL rebuild that didn't have the goal to be bug-compatible near the 100% level doesn't, either, and can be built by a lot of people. Try it yourself: go back to CentOS 5.5 and attempt to rebuild the released sources for 5.6 and get a binary compatible build. I've done it myself for IA64; it was a pain. All of the upstream distributions, Debian, Fedora, etc, have a lot of latitude that CentOS never has enjoyed.
