Missing gems causing Mongrel/Webrick to fail on bootup

Hey Guys,

I recently moved my RoR project to another puter and when I attempted to
start up Mongrel (or Webrick) I got the following message on the Windoze
console…

After about an hour of scratching my head I remembered that my project
needed the sparklines gem. A quick question for the gurus… aside from
relying on my faulty memory, where can I look for diagnostic messages in
the future? The log/server.log file was empty…

=> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000
** Starting Rails with development environment…
