  We show that in gauge mediation models with tree-level R-symmetry breaking
where supersymmetry and R-symmetries are broken by different fields, the
gaugino mass either vanishes at one loop or finds a contribution from
loop-level R-symmetry breaking. Thus tree-level R-symmetry breaking for
phenomenology is either no-go or redundant in the simplest type of models.
Including explicit messenger mass terms in the superpotential with a particular
R-charge arrangement is helpful to bypass the no-go theorem, and the resulting
gaugino mass is suppressed by the messenger mass scale.
