You want to create the project as a BSD Dynamic Library and change the target
to a bundle.  You could've created a Carbon or Cocoa Bundle project but you
don't need the included frameworks and resources so it's just easier to start
with a minimal project such as the BSD Dynamic Library.

After you've included the source files to the project, open the target
settings for your plugin and change:

Linking
	Compatibility Version		<remove value>
	Current Library Version		<remove value>
	Mach-O Type			Bundle

Packaging
	Executable Extension		plugin
	Executable Prefix		<remove value, optional>

GCC-4.0 Language
	Other C Flags			-DSYSTEM=APPLEMAC
	Other C++ Flags			-DSYSTEM=APPLEMAC

<remove value> means to clear the text field for the setting so that its value
is empty.  If you don't see any GCC-4.0 Language settings, it's because you
haven't added your source files to the project yet.  The Other C++ Flags
setting is automatically set when you set the Other C Flags setting.

These are the only settings that must be changed to build a Stata plugin.
It's up to you whether you want to change any other settings.  I do recommend
that you compile the plugin for all Mac platforms by setting the Architectures
setting to "i386 x86_64 ppc ppc64".  You'll build a single plugin that will
work on any Mac.
