Hi

I recently installed Ruby on my new iMac running Leopard and am  
getting the following error when trying to run irb:

dyld: NSLinkModule() error  
dyld: Symbol not found: \_rl\_filename\_completion\_function  
Referenced from: /usr/local/lib/ruby/1.8/i686-darwin8.8.4/  
readline.bundle  
Expected in: flat namespace

I found postings that suggested I re-download the source code, then go  
to the ext/readline dir and do the following:

ruby extconf.rb  
make  
sudo make install

This did not help - I’m getting the same error.

Can anyone help?

Thanks!
