Premature end of script headers

after moving my app to production, I am getting the following error in the apache error log. I am running on linode with apache and passenger.

any help would be great,

thanks,

Jason

Looks like Passenger either doesn’t know where Rails is or Rails might not be installed properly. If you log onto the server at the command line, go to where your app is deployed, start up Mongrel and navigate to port 3000 do you get the same error?
