Dear Jack,

You should read my comments on LDG gauge theory of gravitation in Appendix F of my book:

Gravitation as a Plastic Distortion of the Lorentz Vacuum. For your convenience a copy of the book is attached. You can put a link to the book and to an errata if you think that this is worthwhile. The links are:

A free copy with almost the same material can be obtained from:http://arxiv.org/abs/0909.4472
