  In their original study of conformal gravity, a candidate alternate
gravitational theory, Mannheim and Kazanas showed that in any empty vacuum
region exterior to a localized static spherically symmetric gravitational
source, the geometry would reduce to the standard attractive gravity
Schwarzschild geometry on solar system distance scales. In a recent paper
Flanagan has argued that this would not be the case if the source has
associated with it a macroscopic scalar field which makes a non-zero
contribution to the energy-momentum tensor in the otherwise empty exterior
region. In this paper we examine Flanagan's analysis and show that even with
such long range scalar fields, the standard Schwarzschild phenomenology is
still recovered.
