Changing depends on packages to exact versions will make these incompatibilities rise quickly. Eg: package A should depend on packageB=x.y.z-n That would avoid mixing up different versions. This would avoid a library being updated in a system until all packages that depend on it have been rebuilt. -- Hugo Osvaldo Barrera
