Installing mod_ruby on OS X and Apache 2

Hi, I'm using the latest OS X (I guess that's 10.4.7), Apache 2 and  
Ruby 1.8.4; so far all of these things are working great.  I am able  
to access my server, I can run other scripts -- php for example --  
and I can also run ruby through terminal.  I was even able to compile  
mod ruby successfully, yet everything is not OK.  The problem occurs  
when I try to load a ruby file or even enter a directory with ruby  
support.  I followed the instructions on the Wiki doc and eventually  
created the directory /Library/WebServer/Documents/ruby, when I  
access this directory I get a 500 internal server error.  So I  
checked my error logs and found the following:
mod_ruby: error in ruby
mod_ruby: from /usr/local/lib/ruby/1.8/apache/ruby-run.rb:53in `handler`

mod_ruby: error in ruby
mod_ruby: /Library/WebServer/Documents/ruby:0:in `value`: Thread 
(0x13e5740): deadlock (fatal)

So there's the error, I guess now I should give you a little more  
information about my installation.  Apache is installed in /usr/local/ 
apache2, Ruby is installed in /usr/local/bin, I compiled ruby with  
pthread enabled (a message came up without it enabled recommending  
that I enable it) and with apxs.

I hope that is enough to work with, feel free to ask for any other  
information.  Thanks for any help, Alex.
