As part of a larger project I've been tasked with migrating some existing Ruby on Rails sites (built with an old version of refinerycms 0.9.6.34, at least that's the version listed in the Gemfile included with the source). I don't normally work with Ruby so I'm at a bit of a loss. The previous developers simply handed over the latest git dump as well as a db dump.

I'm working first with trying to get the site up working locally on an Ubuntu 11.10 local machine before pushing up to at test Heroku install. If it's possible to just push directly to Heroku with the files they gave, then I can try that, but it's my understanding I need to get everything working and then use Heroku's tools to deploy.

The previous devs said they're using ruby 1.8.7 so in Ubuntu I've done the following:

aptitude install ruby1.8 ruby1.8-dev ruby1.8-full
aptitude install rubygems1.8

I've restored the database and in the config directory I've made changes to the database.yml to point to the restored database.

When I try and run "bundle install" from the root of the extracted source dir I get:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Obviously the errors with Invalid gemspec need to be resolved, but the other thing that's troubling to me are the lines:

Using refinerycms-core (2.0.4)
Using refinerycms-authentication (2.0.4)
Using refinerycms-dashboard (2.0.4)

Using refinerycms-resources (2.0.4)
Using refinerycms (2.0.4)
Using routing-filter (0.3.1)
Using refinerycms-i18n (2.0.0)

Since the refinerycms version listed in the Gemfile was 0.9.6.34.

When it comes to the Ruby world, I'm a bit lost so any help would be greatly appreciated.

Thanks,
