That would make sense if Rails was autoloading (implicit) this, but it's not -
spec_helper.rb is loading it explicitly. I think the namespace thing is a red
herring.

Which suggests that the config is being silently ignored, even though the
loading is working.

That would never have worked under any version because "include" exposes
methods to the example scope, not the group scope:
describe "something" do
# methods in modules added using extend are available here
it "does something" do
# methods in modules added using include are available here
end
end

My best guess is that you don't need the namespace, and you should leave Rails
out of loading this. Try this:
Dir["spec_helpers/**/*.rb"].each {|f| require f}
RSpec.configure do |config|
config.extend(ModelMacros, :type => :model)
end
That should work to load the file, since RSpec adds"./spec" to the $LOAD_PATH.
If that doesn't work, it might be that ":type => :model" isn't working
correctly, so try "path => /spec\/model/" instead. Please report back and let
us know which, if either, works for you.
HTH,
