OK .. I need help.

According to the info out on the Hivelogic site for Rails to work on OS X I
had to do a build and install of Ruby and Rails to /usr/local.  I did so
and Rails is working fine.  However when I try to use irb I get this
error ..

salamanca:~ jna$ irb
dyld: NSLinkModule() error
dyld: Symbol not found: _rl_completion_matches
  Referenced
from: /usr/local/lib/ruby/1.8/powerpc-darwin8.4.0/readline.bundle
  Expected in: flat namespace

Trace/BPT trap

If I use the installed /usr/bin/irb everything works fine.  What did I
break?  Another question is if the Hivelogic info is correct.  Is there a
way to get Rails working with stock OS X ruby.

(I have OS X 10.4.3 which comes with Ruby 1.8)

All comments welcome .. PLEASE
