I solved some of the remaining failures with the forrestbot. Both "forrest-site" and "forrest-docs-dev" needed to have a full 'svn checkout' done before the forrestbot starts. Forrestbot only does 'svn co' of part of the source tree and so it misses the "conf" directory for "forrest-site". Dunno what the issue was with "forrest-docs-dev", but the full checkout fixes it. So now we are down to minor build issues and weird error messages about logging.
