VirualBox 4.0.2: Guest Additions needed for the Mac OS X

A VirtualBox guest OS is practically unusable unless the Guest Additions package is installed.  It allows a practical video configuration, access to the USB hardware, and more complete integration with the mouse.  There are probably other features I'm not listing.

Bad news ... Guest Additions are not currently available for OS X.  Yeccccch!

I have used VirtualBox on Linux host systems with XP guest OSs and have had good results.  Now, I have a Mac and want to accomplish the same.  No joy.   VirtualBox documentation, chapter 14 says:

VirtualBox does not provide Guest Additions for Mac OS X Server at this time.

If you find the package, please let me know!  Trying to save you a little searching ...
