The version-release of rsnapshot in FE4 is newer than the one in FE5 and devel: rsnapshot: 4: 0:1.2.9-4.fc4 (FE4) 5: 0:1.2.9-2.fc5 (FE5) 6: 0:1.2.9-2.fc6 (FE6) Fix: bump FE5 an devel to something >= 4%{?dist} and rebuild. The FE4 bumps seem tho have been made without a changelog entry. If you need to fix something in an old distro branch, append a dot and a digit *after* %{?dist} so that there's no need to rebuild everything for all newer branches too. https://www.redhat.com/archives/fedora-extras-list/2006-May/msg00083.html
Sorry, I got caught in the "make tag" nightmare where it creates the tag but fails to build because of a not-checked-in file. The fc4 bump was purely to compensate for that. Should be fixed now.
Sure, thanks, but in the future, if you need to similar things, the link in the initial comment contains a recipe for doing it in a non-intrusive way (eg. 2%{?dist}.1 instead of 3%{?dist} in the old distro only).
