more changes to compile darwin

this should represent the last major changes to get darwin to **compile**.  again,
the purpose here is to get darwin to compile so that we can eventually implement a
ci task that would protect against regressions for darwin compilation.

i have left the manual darwin compilation largely static still and in fact now only
interject (manually) two build tags to assist with the build.  trevor king has great
ideas on how to make this better and i will defer final implementation of those
to him.
