We compute the zero temperature phase diagram and the Hall response of the doped perovskite manganites within the model of double exchange and Jahn-Teller coupling, employing the d -> inf approximation proposed by Millis, et al. We find that in this scenario a "hole-like" R sub H for the hole doped manganites, as observed at low temperature by Matl et al, can be obtained only when lattice distortions persist in the metallic state as T -> 0. The calculated temperature dependence of R sub H seems to be consistent with the measured "normal" Hall coefficient in thin films.
