I'm running ruby 1.8.5 (2006-09-10) [powerpc-darwin8.7.0] and when I try they little simple Tk application on the first page of the Ruby Tk chapter of the Pickaxe Book I get:
~ $ ruby -w TK.rb
./tk.rb:7: uninitialized constant TkRoot (NameError)
from TK.rb:6:in `require'
from TK.rb:6
However if I run the pre-installed ruby that came with Tiger like:
~ $ /usr/bin/ruby -w TK.rb
I get a nice little window with "Hello World!" in it as well as ruby, File and Edit menus. The archives seem to have quite a bit of discussion of this issue but I couldn't find any resolution. Did anyone figure out how Apple got Tk working?

I suggest you check $: for where your Ruby is looking for libraries and then verify whether or not tk.rb is available in one of those libraries. I think it's likely that it's not.
Ruby 1.8.2 finds tk.rb in /usr/lib/ruby/1.8. but I don't know if this version will work with 1.8.5.

Good catch, Morton. tk.rb is nowhere to be found in any of my $LOAD_PATH files. I still don't understand why I get the 'uninitialized constant' message rather than 'no such file to load' but the problem is that there really isn't any such file to load.

Seven Deadly Sins? I thought it was a to-do list!
OK, I thought I might be able to fix the problem by modifying my test program as follows:
$: << '/usr/lib/ruby/1.8/powerpc-darwin8.0'
require '/usr/lib/ruby/1.8/tk'
root = TkRoot.new {title "Ex1"}
TkLabel.new(root) do
text 'Hello World!'
pack {padx 15 ; pady 15; side 'left'}
end
But now I get:
~ $ ruby -w TK.rb
dyld: NSLinkModule() error
dyld: Symbol not found: _is_ruby_native_thread
Referenced from: /usr/lib/ruby/1.8/powerpc-darwin8.0/tcltklib.bundle
Expected in: flat namespace
Trace/BPT trap
All I can figure out from this is that the old version of tk.rb is loading a dynamic library and the dynamic loader can't resolve a symbol. I'd appreciate any pointer but I suspect that this is best pursued on one of the Apple mailing lists.
