log access denied

Problem: Mongrel cannot start because access to log is denied. I just switched to a new development laptop (Snow Leopard). I think I installed everything I needed. I git clone the application I am developing from the repository. Everything went fine. Now when I run script/server, this is what I get:

=> Booting Mongrel => Rails 2.3.5 application starting on http://0.0.0.0:3000 /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ 1.8/logger.rb:518:in `initialize': Permission denied - /Users/chief/ Documents/my_app/log/acts_as_ferret.log (Errno::EACCES)

Please help. Thanks.

So, what are the owner/permissions on that file, and what user are you trying to start the app as?

Thanks Hassan for your prompt response. I am trying to start mongrel when logged in as a regular user. The log file somehow is owned by root. I suspect that is because I am having apache and passenger running at the same time trying to serve the same app. I'll try to disable apache.

After I run chown on the log files to take over ownership of the log files, it works now. THanks.
