Redmine

Hi,

I am trying to upgrade from version 1.3 to 1.4.1 on step 6 of the migration guide http://www.redmine.org/projects/redmine/wiki/RedmineUpgrade#Step-1-Check-requirements I get an error saying something is missing. The database I am using is mysql. Below is the commands I executed and the outputs

redmine@redmine:~/redmine-1.4.1$ sudo rake config/initializers/session_store.rb

An error occured while installing pg (0.13.2), and Bundler cannot continue.
Make sure that `gem install pg -v '0.13.2'` succeeds before bundling.

I tried the gem install pg command suggested but it did not work either. Can somebody help?

Thanks
