I am fairly new and just installed the following:

I am running on OSX 10.4. 10  
I followed Hivelogic versions and installed  
ruby 1.8.6 (2007-03-13 patchlevel 0) [powerpc-darwin8.10.0]  
rails 1.2.3  
mysql Server version: 5.0.41 MySQL Community Server (GPL)

I am getting this error when trying to run a very simple app.

dyld: NSLinkModule() error  
dyld: Symbol not found: \_rl\_filename\_completion\_function  
Referenced from:  
/usr/local/lib/ruby/1.8/powerpc-darwin8.10.0/readline.bundle  
Expected in: flat namespace

Trace/BPT trap

I think this is a OSX/Ruby bug.  
Because I am a newbie, I need explicit help with the fix.
