It was just added and it's a beta, but it's the last(!) application (with koffice 1.x) that has kdelibs-3 version in stable. I'm leaving the decision to you, if you want to have rosegarden stable version... this is it. Remaining kdelibs-3 pkgs will be lastrited 2010-01-01 (that is, old rosegarden, koffice 1.x and remaining kde-base/ deps that was kept only for koffice 1.x)

x86 stable
amd64 stable
ppc: The old version was lastrited and removed because this took too long, as such, it isn't blocking bug 287583 anymore. (The old version had kdelibs:3.5 deps and wasn't even installable)
Marked ppc stable, closing since we're the last arch.
