Advanced users might build with gcc from MacPorts, but the default

but still allow users to explicitly specify gcc if they have a
different installation.

docs: pass the docs version from automake
docs: merge the admin ad sdk guides back into one doc

Merge the admin istrators guid and the SDK. This allows us to add

like to later add API reference and command-line references.
