I'm not sure why 'osc build' does not find the packages from Essentials: unresolvable: nothing provides libdvbpsi-devel < 1.0, nothing provides taglib = 1.6.2 needed by taglib-devel taglib and libdvbpsi builds fine. Maybe the prjconf is broken? Why is there a '=' appended? .osc/_buildconfig-openSUSE_11.4-x86_64:Substitute: pkgconfig(libvlc) vlc-devel= Olaf
