Personal experience --

>> require 'tk'
LoadError: no such file to load -- tk
	from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'

Also, I read it on the Web. I don't remember the exact page now, but I
did just find this one:
<http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/22e0e72994155258>

Sure enough, there is no tk.rb under /System/Library/Frameworks/Ruby.framework.

When I have time I will try recompiling it.

Now that I think about it, I downloaded and installed RubyCocoa, so
that should have overwritten the RubyCocoa that came with the OS,
right? Or would that just replace the Cocoa-specific parts, and leave
the core Ruby stuff in place? (If I compile my own Ruby, I don't want
to lose the Cocoa-specific parts.)
