NGINX with passenger can't find rails app running on Mavericks

Nope. Same error. I tried with "/Users/gabrielmadeira/Google\ Drive/Apps/Rep/public"; but didn't work either... I can't figure out what is going on. The conf file is like that now:

user  gabrielmadeira staff;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

}

The error has gone with this configuration:

   server {
           listen       80;
           server_name  rv.local;
           rack_env          development;
           root   "/Users/gabrielmadeira/Google Drive/Apps/Rep/public";
           access_log "/Users/gabrielmadeira/Google Drive/Apps/Rep/log/nginx_access.log";
           error_log "/Users/gabrielmadeira/Google Drive/Apps/Rep/log/nginx_error.log";
           passenger_enabled on; 
   }

but now the application is not showing my show page.... instead a blank page is shown...
