Yes.  An excellent reference for this is Petr Beckmann's "Einstein Plus
Two."  And all you need is speed of gravity.  (By the way, there are NO
errors in Gerber's work.)  Pauli et al dislike Gerber's derivation because
it is not a complete theory of gravity.  Not because there are errors in
Gerber's work.  (At least no errors have ever been published or noted in
what Gerber actually DID.)  GR's results are also the result solely of
finite gravity speed.
