After switching to Rails 3 you may get a LoadError
with the following message when trying to use your application via passenger:
no such file to load -- dispatcher
Your Passenger version is most likely out of date.
Update the gem, then install the apache module again:
sudo gem install passenger
sudo passenger-install-apache2-module
Follow any instructions. Update your /etc/apache2/httpd.conf
with the lines given at the end of the installation process to use the version you just installed.
