Subject: irb completion fails on Intel Mac with ruby-1.8.5

Building ruby-1.8.5-p12 on OS X 10.4 gave me an irb that
supported command completion, but did not have support
for vi_editing_mode.


% irb
irb(main):001:0> Readline.vi_editing_mode
NotImplementedError: the vi_editing_mode() function is unimplemented  
on this machine
         from (irb):1:in `vi_editing_mode'
         from (irb):
         from :0

Which essentially meant it was stuck in emacs editing mode.
I then added readline from darwin ports and rebuilt ruby:

sudo port install readline
.. install ruby

But, now I irb won't even run:

  % irb
dyld: NSLinkModule() error
dyld: Symbol not found: _rl_filename_completion_function
   Referenced from: /opt/local/ruby-1.8.5-p12/lib/ruby/site_ruby/1.8/ 
i686-darwin8.8.2/readline.bundle
   Expected in: flat namespace

My next attempt will be to install the gnu readline and retry.
But, while I do that, does anyone know if this is a known problem and  
how to fix it?

Thanks

Jim
