Perhaps I chose my words poorly...
What I meant is, is there any group or someone who is a Mac OS X nut that has released a pre-configured version of linux that has its UI tuned to act like OS X while still being a linux distro that is able to run my choice of desktop linux apps.
Maybe what I'm looking for is just a great and up to date howto with plenty of handholding for the superkarmba stuff.
I have a pretty okay idea of how to do certain things, but it isn't all super-easy.
If you look at XPde for example, http://www.xpde.com/index.php
you'll see a Windows XP version of what I'm talking about. In their case, they want to make it easy for Win XP users to migrate to Linux by giving them a familiar look and feel. I wonder if anyone has done similar (if not as thorough) work on an OS X-like project.
