I read the release message -> "Rails 3.0: Second beta release"
-> from
rubyonrails.org

http://weblog.rubyonrails.org/

Note that Ruby 1.8.7 p248 and p249 has marshaling bugs that crash both 
Rails 2.3.x and Rails 3.0.0. Ruby 1.9.1 outright segfaults on Rails 
3.0.0, so if you want to use Rails 3 with 1.9.x, jump on 1.9.2 trunk for 
smooth sailing.

===============================================
and, someone suggested that I delete config.ru or change nginx.conf as 
below :

* rails_env development; -> rack_env development;

server {
        listen 3001;
        server_name horn.local;
        root /Users/shajun/project/horn/public;   # <--- be sure to
point to ''public''!
        passenger_enabled on;

        "rails_env development; -> rack_env development;"

     }

but I could not decide this question.

===============================================
Thank you very much again! Conrad

in /opt/nginx/conf/nginx.conf

passenger_ruby /home/wayne/.rvm/bin/passenger_ruby;

instead of

you current ruby version as "ruby 1.9.2-head..."

========================================
and then when I input localhost:3002 in browser and click link - > About 
your application’s environment

I''m having this same issue, but on Apache with Rails 3 Beta 3. I
noticed
that your Ruby version is now 1.8.7 and not 1.9.2. I''m trying to figure
out how to get past the "no such file to load -- rack" issue while 
keeping Ruby 1.9.2.

I tried your approach of changing passenger_ruby to the home directory 
instead of using the "ruby 1.9.2-head" directory but my home directory
is empty. I installed RVM via git so the closest matching folder I can 
find is in /root/.rvm/src/rvm/bin/ but I don''t have a passenger_ruby 
file in there.

I''ve tried everything I''ve found on Google as possible
solutions and
can''t get it to work.

Any advice?
Thanks
Bobby

Re: rails 3 b2+nginx report error "no such file to load --

nevermind, got it working. Once I fully understood all of these 
directions: http://rvm.beginrescueend.com/integration/passenger/ I got 
it working. Needed to make sure that PassengerRuby was pointed to 
something like: /home/wayne/.rvm/bin/passenger_ruby instead of the RVM 
ruby
