I know under the lib/ruby directory  
the 1.8 directory holds built-in and standard library Ruby source code  
and  
the gems directory holds Ruby source code for libraries install as gems.

What gets placed in site\_ruby? Is it libraries not installed as gems?  
Why does it contain tk code?

site\_ruby (named in convention with site\_lisp and others) is a  
standard location for (you guessed it) libraries.

If it contains tk code, I’d bet that something installed it there.  
Neither of my installations (one came with OSX, the other built from  
source) contains anything to do with tk.
