Here is the bug: https://bugzilla.redhat.com/495200 After gnome-build got merged into Anjuta, I had added the following to anjuta.spec: Obsoletes: gnome-build <= 2.24.1-1 Provides: perl(GBF::Make) = %{version}-%{release} It was not entirely clear to me from the guidelines [1] whether to add a 'Provides: gnome-build = %{version}-%{release}' or not. It seems like adding it is not making much of a difference if I have an old F10 gnome-build package lying around and I am trying to install a F11 anjuta package. I am sure my knowledge of Obsoletes and Provides is not really upto the mark here, so any help would be much appreciated.
